Beavis and Butt-Head

Liar! Liar! is the 32nd and final episode in Season 4 of Beavis and Butt-Head. It is the 89th episode overall.


Beavis and Butt-head are working at Burger World while their manager is counting money from the cash register. When the manager notices that the till is short, he has them take a lie detector test to see if they stole money. Butt-head tries to pass the lie detector test by holding his breath but he passes out. Beavis, however, couldn't get a base reading on the lie detector so the interrogator requests that Beavis just say anything. Then Beavis says he killed a bunch of people once. This leads the police to think that Beavis is the Hippie Ripper, an infamous serial killer from 1969.

  • Maggie Estep - "Hey Baby"
  • Rollins Band - "Liar"
  • Helium - "XXX"


  • This episodes reveals that Beavis once killed a bunch of people, which makes the bulb on the lie detector flash green. Later, police believe that Beavis is the Hippie Ripper. The reason police believe this is that Beavis thinks he killed people and the lie detector believed it.
  • At the time this episode aired, Beavis wasn't allowed to say fire. So instead of saying "Liar liar pants on fire", he says "Liar liar pants on...Whoa!"
  • The episode includes references to George Orwell's "1984". The test is given by "Mr. O'Brien", who at one point asks Butt-Head, "how many fingers am I holding up?", to which Butt-Head answers "four", triggering a truthful reaction. O'Brien remarks that even though he wasn't really holding up four fingers, the truthful reaction was where Butt-Head believed there were indeed four fingers.
  • Mr. O'Brien's assistant is named Julia; a reference to Winston Smith's clandestine lover in "1984".


[We open at Burger World, where we find the manager counting the money in the cash register, along with Beavis and Butt-Head, who try to interrupt him while he's counting.]

Burger World Manager: 50, 60, 65, 70-

Butt-Head: 12!

Burger World Manager: Shut up! 75, 80-

Beavis: 25 cents!

Butt-Head: Uhhh, 69!

Beavis: "Number Two"!

Burger World Manager: 83, 84 - SHUT UP!!! 85, 86...

Butt-Head: 4!

Beavis: O! ONE! ONE!!!

[The manager finally finishes adding up the money and pulls out a receipt.]

Burger World Manager: It's still short, fellas.

Butt-Head: Uhh, better count it again, sir.

Beavis: Yeah, you didn't get the pennies.

Burger World Manager: No way, guys! We're still missing money.

Beavis: [He starts to become frantic for no reason.] I DIDN'T DO IT!! I DIDN'T DO IT!! It was, like, a foreigner.

Butt-Head: Yeah. [They start laughing at Beavis' comment.]

[Soon after, they're sent to an optometrist for a polygraph test. Inside, Beavis continues to act frantic.]

Beavis: I didn't do it! It was a foreigner!

Butt-Head: What are you doing?

Beavis: I'm practicing. [He pauses for a moment, not knowing why they're there in the first place.] Hey, Butt-Head. What are they gonna do to us?

Butt-Head: Uhh, I think they're gonna, like, give us one of those polygrip tests, or something.

Beavis: Oh yeah! That stuff is pretty cool. I found some of that stuff at Anderson's house, and it's like, I put it on my teeth, and I was going like... [He starts making a face, simulating his teeth getting stuck together.]

Butt-Head: No, dumbass! It's, like, this lie-detector test.

Beavis: I DIDN'T DO IT!!

Butt-Head: Shut up, Beavis! Hey, check this out. When you're taking the lie detector test, just, like, hold your breath.

[Beavis begins to do so, which causes Butt-Head to slap him.]

Butt-Head: Not now, dumbass!

Beavis: Oh, sorry, Butt-Head. I was just, like, practicing and stuff.

Butt-Head: Beavis, you suck as a liar.

Beavis: "LIAR!" "LIAR!" [He starts to sing.] LIAR - LIAR - PANTS ON... [But he stops for obvious reasons...]

Optometrists's Assistant: Head? Butt-Head?

Butt-Head: Uhh, yeah?

Optometrists's Assistant: Mr. O'Brien will you see now.

[Butt-Head goes into the office to begin his polygraph test, leaving Beavis behind.]

Beavis: I DIDN'T DO IT!!

[Inside the office, we find Butt-Head wired with electrodes hooked to the polygraph machine.]

Mr. O'Brien: Alright, now I'm going to ask you a series of questions. Failing to be truthful in your responses will be interpreted as an acknowledgement of guilt. Do you understand?

Butt-Head: Uhh, yeah. [The polygraph machine indicates he is lying about understanding.] I mean, no. [The polygraph now confirms he doesn't understand at all.]

Mr. O'Brien: Just tell the truth and you'll have nothing to worry about. Let's begin. [He turns on the machine's printer, and Butt-Head takes a very deep breath, then holds it.] Ok, please tell me your name.

Butt-Head: "Butt-Head". [The polygraph confirms he's told the truth.]

Mr. O'Brien: Ok, good. Now can you tell me how many fingers I'm holding up?

Butt-Head: Uhh, four? [The polygraph confirms he's correct, however...]

Mr. O'Brien: Well, it's three, actually, but since you thought it was four, you didn't really lie, so that's good! Now, Butt-Head, tell me. In all of your life, have you ever stolen anything?

[Because Butt-Head has been holding his breath for so long, he's causing the machine to malfuncition. Meanwhile, Beavis continues to assume his "innocence" in the waiting room.]


[Back in the office, Butt-Head's beginning to turn purple from holding his breath, and the machine begins to break down.]

Mr. O'Brien: I'll repeat the question. Have you ever stolen anything?

Butt-Head: Uhh... Uhh... [He finally passes out from lack of oxygen, and the machine pops a fuse and breaks down finally.]

[Outside, Beavis continues his "pleas", finally confirming that...]


Optometrist's Assistant: Beavis? Mr. O'Brien will see you now.

[Once inside, Beavis is getting the electrodes attached to his head, his arms, and his hair for some odd reason.]

Beavis: Are you gonna put one on my nads?

Mr. O'Brien: Julie, I'm not getting a reading here. Could you check those connections for me? [His assistant goes to do so.]

Beavis: Because, uhh, you can if you want to. You know, put them on my nads.

Mr. O'Brien: Good! Well, young man, I'd like to get a base reading here. Could you say something for me, please?

Beavis: Umm, ok.

Mr. O'Brien: Just say anything. Anything at all, the first thing that comes to mind.

Beavis: Umm, I killed a bunch of people once! [Because the polygraph was broken by Butt-Head, his comment was falsely confirmed as being the truth. Beavis then starts holding his breath, and the machine malfuncitions even more!]

[Later that day, Butt-Head is watching the news at home, when a special report begins to air about Beavis getting arrested for a crime that has now been pinned on him.]

Newscaster: Authorities are saying that tonight, they have finally found the killer in the infamous "Inna Gadda Da Vida" slaying some 35 years ago. Police say this boy- [A mugshot of Beavis now appears] -is the so-called "Hippie Ripper" who, in 1969, killed 15 hippies who were sleeping in a van outside of Highland.

Butt-Head: [He laughs.] "69"! [He drinks from his Mega Gulp cup.]

Newscaster: When asked how a teenage boy committed a crime that happened almost two decades ago, a police spokesman said, quote: "He's very clever."

Butt-Head: Get a haircut, hippie!
