I find Dr. Who quite funny, and the cartoon Regular Show.
Oh, I could list so many people and things...
I have an unreasonable love for Muscle Man My son's best friend looks just like him (minus the green skin and mullet); every time he comes over, I giggle
More funnies:
Little kids
Monty Python
Billy Connolly
John Irving
The IT Crowd
Bringing Up Baby (or pretty much any screwball comedy)
