Serenity was funny (and I got onto watching the entire firefly series and that was pretty funny too). Team America kicked arse as well. An obscure one I'm going to name is a Hong Kong movie "Ji Long Chuen Suet" (Legend of the fight wolves?), it was starred and directly by Yan-Ji-Dan and had Wong Ji-Wah (yep, him in a martial arts flick), Wong ji-wah was funny, and some of the corny elements and really bad props (it was obvious they blew the budget towards the end) really adds to the comedy value.
