well for E4 thursdays are funny-est so its the great trio of My Name is Earl, then Big Bang Theor followed by Inbetweeners. Out of thse Inbetweeners wind cos it is very funny and so childish yet true to life reprisenation of 6th form life and its Englash.
South park is absolutely hilarious, but i really like to wath everybody loves raymond. The more you watch the shows the funnier they get, because you catch on to the " disfunctional family" jokes.
Family Guy is funny, Daily Show with Jon Stewart, Ten Items or Less, most of the late night shows are funny too. I especially like David Lettermam, Jimmy Fallon, and Conan Obrien. Jay Leno was ok, but I thought he could have been better.
Reno 911. Psych is totally underrated. It's flippin hilarious people Yes, South Park is funny. I have to sneak away to watch it though, cuz I'm still not allowed...
