It would seem that season 3 was the shortest ever in TV. If you go to olink you can watch some past episodes. Also try link And link. If they don't have Psych try watching Chuck. It's funny and clever sometimes. Have fun.

Maybe it was so short because of the writer's strike that year?

OOHH! I like Chuck, too!! It's good.

Um, season 3 hasn't finished airing yet - there are going to be 8 more episodes, starting on the 28th November (it's currently on hiatus)
Season 2 was the one that aired during the writers strike, and that had a full season too.

I sound really annoying, sorry. :(
