The only semi-original jest that I can claim to have invented (ca. 1996, on the way to a Boy Scout meeting):

Question: What's black, has a white or yellow stripe down the middle of its back, and goes "Cluck, cluck, cluck"?

(...drum roll...)

Answer: I don't know, but it's what you get when you cross a chicken with a road!

(groan)

OK, so maybe it's not really a joke — it's a joke about a pun about a joke ....

(See CoarseCorrection for another original joke by ^z - RadRob)
