There are a couple hilarious Hulu exclusive shows that Throbble and I have been watching recently.
These shows are free, they do not require a Hulu Plus account to watch:
Quick Draw (8 Episodes)
Wild west comedy set in Great Bend, Kansas (near Dodge City). The writers write all the overarching plot and scenes but all the dialog is improvised.
It's got a Harvard educated sheriff who is new to town, a whore house run by his girlfriend, an uneducated but insightful deputy, and an undertaker who got the job because he's good at making boxes.
Moone Boy (6 Episodes)
Co-written and co-staring Chris O'Dowd. (Roy from the IT Crowd.) It's about a naive 12-year-old boy from a fucked up family in 1989 who has an imaginary friend named Sean Murphy (Chis O'Dowd). Good stuff.

EDIT: Restored the description for Moone Boy which was cut off by an invalid apostrophe.
