Futurama(1999 - 2013)
A comedy from the creators of "The Simpsons". A pizza delivery boy named Fry accidentally gets cryogenically frozen and awakens in the year 3000. He adapts to life in the 31st century and works for his great-great x20 nephew's intergalactic delivery company.
There's a great cast of characters, including Leela, a cyclops woman who was orphaned as a child (and Fry's crush); Bender, a loud mouthed beer guzzling robot; Zoidberg a crustacean like alien who is often times the butt of the crew's jokes; and Zapp Brannigan, an idiotic windbag general who thinks he's God's gift to women.
The show was hysterical, but was cancelled after its fifth season. However, after the successful comeback of Family Guy, Matt Groening has decided to release several staright-to-DVD Futurama movies, which, if successful, will bring Futurama back. Reruns currently air on Adult Swim.UPDATE:it was recently announced that Comdey Central ordered a season of Futurama.It will be back in 2008. It is also aired on Cartoon Network at night at 10:30 and 11:00
