One of the more obscure reasons I love Futurama is because they cast Katey Sagal as Leela.

Married With Children is one of my guiltiest of pleasures.
(And I like the little connection with her and Groening's The Simpsons when in the excellent 'Homer In Space' episode they did a quick parody of Married With Children - PEGGY: Al! Let's have sex! AL: No, Peg. [FLUSHES TOILET STANDING IN THE LIVING ROOM. HUGE AUDIENCE APPLAUSE AND CHEERS.])
