Sitcoms love having guest stars, and sometimes they're even able to rope in famous bands and musicians to give a performance! However, these can often be a pretty weird fit, as you'll see in these 10 clips.
Married... With Children - Anthrax
The thrash metal band shows up to the Bundy house after the kids win a contest, and proceed to play "In My World" as everyone trashes the place. Pure heavy metal greatness.
Punky Brewster - Andy Gibb
When Punky gets a new piano teacher, it turns out to be former teen idol (and youngest brother of the BeeGees) Andy Gibb! It would unfortunately be his last screen appearance before his death three years later at the age of 30.
Square Pegs - Devo
An often-forgotten sitcom that launched the career of Sarah Jessica Parker, Square Pegs featured the band best known for "Whip It" on an episode. Apparently the band was severely uncomfortable with the amount of drug use happening on set.
The Cosby Show - Stevie Wonder
The icon wore one of the ugliest, most 80s sweaters imaginable while running through one of his hits for the Cosby family.
