I was looking for a trailer for Stephen Tobolowsky's Birthday Party, which I got for Christmas. I like this clip better than the trailer. :)
The movie is just Stephen telling stories -- true stories, from his vast acting career and before. He's an excellent storyteller, and this film will almost definitely be a go-to movie for me. I've watched it already (along with most of the 90 minutes of bonus stories) and I'm itching to watch it again.
To get a good sense of the film, check out The Tobolowsky Files, a free podcast wherein Stephen Tobolowsky tells more stories, most not contained in the film.
Edit: I found a good trailer:
