Remember the episode where Raj went out with this older lady. She had given him a pipe belonging to her dead husband and he thought she liked him. Actually, the show wasn't that funny except for two parts:

The part where she came over with her boyfriend. They took Raj to the theatre or something. Watch Raj's reaction as he closed the door. LOL. He didn't even want to go.

The second one was after Raj arrived home and Dwayne and Rerun were watching TV. I liked the way Rerun said "Hey Ra" as he trying to sneak past both of them.

I don't know if this qualifies as a funny episode, but "Shirley's Cookies" wasn't a bad episode.
