Do you think Jesus has a sense of humor?

The Bible portrays Jesus during His earthly ministry as being a pretty serious guy. Why not?After all, He had the weight of the world on His shoulders. Yet I wonder, inasmuch as the medical profession admits that laughter is good medicine, and Proverbs 17:22 says "A merry heart doeth good like a medicine", do you suppose that if He was here today He would enjoy sitting in the audience while Steve Martin or Robin Williams did their comedy routines?
