Dallas Grimes is the main antagonist of the 1996 animated satirical comedy film Beavis and Butt-Head Do America. She is a beautiful, crafty arms dealer who steals the bio-weapon X-5 Unit and uses Beavis and Butt-Head to take it to the US Capitol in exchange for sex, although she is really seeking to retrieve the unit and eliminate the duo.

She is voiced by Demi Moore.

Beavis and Butt-Head Do America[]

Dallas' role is first mentioned in the movie when her husband Muddy Grimes is asking a friend to send men to have her killed and to take the X-5 Unit. She is first seen when Muddy hands a picture to Beavis and Butt-Head when he mistakes them for the hitmen. Muddy assigns them to "do" his hot wife and offers an amazing award for it.

When Beavis and Butt-Head find her in Las Vegas, Dallas is about to shoot them when she meets them in her hotel room, although she realizes they are practically harmless and really stupid. She asked them how much Muddy was paying them to kill her, Butt-Head said, "10 uh." Dallas took that as an insult, "10 Grand. Oh that Cheap-Ass." She at first asks them to go and "do" Muddy for twice the money, although it is then when she realizes that they think to "do" is to have sex. When Beavis takes his pants off and fights Butt-Head on who gets to "do" her, she takes the pants and sews the X-5 Unit into it. She tells them to meet her at Washington D.C. and she will give them what they want.

Later on, she's given a cavity search by FBI Agent Hurly (which she sarcastically hints to have enjoyed and says she wouldn't mind another), and confesses that the unit is really is in the pants of one of the boys. In Washington D.C., Dallas sees the boys and parks the car to meet up with them to recover the weapon, but Muddy shows up. He decides he should just kill her himself when the duo go missing until she seduces him when she says that they'll "both kill them" and has sexual intercourse with him in his car. When they are found and arrested, Muddy thinks that they are back together, although it turns out that Dallas just seduced him to not kill her and they are both placed under arrest. She is last seen in the secured truck when Tom Anderson is mistaken for the real suspect and thrown into the truck under arrest.

Video Games[]

An enemy in the 1998 Game Boy game looks a lot like Dallas, she walks around the level and touching her damages you.

Physical appearance[]

Dallas is considered to be a slim and attractive lightly tan-skinned woman with bra-length or mid-back length blonde hair that has brown roots on top of her head (indicating that she's a natural brunette), green eyes with blue eyeshadow, red lips and red nails.

She is seen sporting a cropped light blue button-up shirt with a knot in front, dark wash mid-rise jeans and ankle black heeled-boots.


In comparison to her more temperamental husband Muddy Grimes, Dallas is a cool, calculating and level-headed woman, but not above having a sense of humor. She is also a mistress of improvisation and an expert seductress. When she first assumes that Beavis and Butt-Head are authority figures or men hired by Muddy to kill her, she holds them at gunpoint.

However, when she realizes that they thought "do" meant sex with her, she finds herself laughing to herself before using the opportunity to her advantage, seducing them into telling them to meet her in Washington D.C, while she hides the X-5 Unit in Beavis' pants. She also seduces Muddy to lower his guard before ATF busts them. Despite that, she is also known to be treacherous, going so far as to turn Muddy in for a reduced sentence.


  • Despite the fact that Dallas is the main antagonist, she was never the one behind Beavis and Butt-Head's adventures.
  • At the time of the film's release, Demi Moore (Dallas' voice actress) was married to Bruce Willis who provided the voice of Muddy Grimes.
  • Dallas fills a very similar niche to Serena Ryan from the Beavis and Butt-Head Do the Universe movie, particularly with the boys' desire to "score" with Dallas driving the plot of the Beavis and Butt-Head Do America movie, much like with their attraction to Serena in the second movie, but ends up being a very different kind of antagonist. However, Serena and Dallas have very different characteristics from each other:
    • Dress-wise, Serena dresses more modestly while Dallas tends to wear more skimpy clothing by comparison.
    • While Serena managed to lead a more legit political career and whatever corrupt, criminal things she did were done in secrecy without exposure, Dallas was an open criminal and terrorist.
    • Serena was shown to act genuinely friendly with Beavis and Butt-Head to begin with and despite growing more hostile to them throughout the movie, she eventually gives up on that hostility and consents to their desires, albeit with some small reluctance. On the other hand, Dallas was openly hostile to the boys to begin with and despite acting seductive to get what she wanted out of them, she had no intention of ever "scoring" with them.
