How about a DVD box set of classic sketch comedy shows such as "Monty Python's Flying Circus" or "Kids in the Hall"? Alternatively, you could get tickets to see a live sketch comedy show in his area. You could also get him a book about sketch comedy, such as "Live From New York: An Uncensored History of Saturday Night Live" by Tom Shales and James Andrew Miller. Additionally, consider a sketchbook and a nice set of pencils or markers for him to create his own sketches.
Or you can get him a star map with an important date you share.
