The AT&T of sketch shows. Aired from 1995-2009. Unlike other sketch shows- it was not live. Some people liked it others fucking hated it. The cast was mostly comprised of C-list improv actors and stand-ups. The writing mostly sucked but the cast wasn't terrible. Generally the show was either doing okay or sucking donkey dongs.
Despite the name, it had almost no relation to the popular MAD magazine.
Not the worst sketch show in the word (it's Turn-On, wikipedia the show) but is out of SNL's league with 5 season exceptions.
Rotten Tomatoes; 6.0/10 fresh
Joe; Just saw Madtv last week.
Joe; You know, that sub-par sketch show.
Jon; Yeah, I still have no clue.
Joe; Forget it
