"Here Comes the Bride's Butt" is the 30th episode of season 5 Beavis and Butt-head. It first aired on June 9, 1995.
Beavis and Butt-head walk by a church and see that a wedding ceremony is about to happen. Butt-head says he has heard that the bride is expected to "put out" on her wedding night, not understanding that the honeymoon is only for the bride and her groom. So, the two attend the wedding, expecting the bride to have sex with them. At the ceremony, the two are incredibly confused and bored. They leer at the bride when she walks down the aisle past them, and they vocalize their objections to the marriage, though they are ignored. When the minister says "You may now kiss the bride", Beavis and Butt-head run up to the altar because they think they are allowed to kiss the bride. Their attempt to do so gets them thrown out of the wedding. Tom Anderson and his wife Marcy walk by and Tom reminisces about their own wedding. Beavis and Butt-head decide that marriage must suck because you must hang out with the same person all the time and say the same things for years and years. (a clear description of their own relationship) Tom Anderson and Marcy walk off into the sunset hand in hand, with Beavis and Butt-head behind them, laughing and insulting each other.
Either Sam Gluckman, the bank manager from Jump!, or Harry Buddisker, the health inspector from the episode Closing Time, who resemble each other, appears as the father of the bride. The sign outside the church says 'Buddisker and Gluckman Wedding Today' leaving it ambiguous which of the 2 men it was.
