Re: Best pure humor episodes
For honorable mention, even though it is not a comedy episode in the slightest, I would nominate the teaser from "The Pegasus." The entire Captain Picard Day scene is hilarious, IMHO. Stewart and Frakes sell it brilliantly.
Yeah, it's at times hard to believe that scene is from The Pegasus, given that the rest of the episode is so deadly serious. The same episode which has Riker facing actions from his past which could potentially end his career starts off with Riker playing with a Captain Picard doll.
