Married with Children is a classic from the late 80's to the mid 90's. It is a Fox show so it is vulgar and crude as much as network TV could get. At a time when classic sitcoms were on like Seinfeld, Cheers, Who's The Boss, and Roseanne, Married with Children offered hilarity beyond anything else.
It usually featured Al Bundy, the protagonist, making fun of fat women. The following is a medley for your enjoyment.
