Best joke I've ever read

Q.	If you paddle up a canoe, and a tire falls off, how many pancakes can fit in a doghouse?
A.	None. Ice cream doesn't have bones!

From here.

BTW, did you know that the "elephant joke" was invented in 1962?  It's true!  On a related note, I once passed by a gaggle of Comp. Sci. grad students who were with a visiting professor from Israel.  They asked me to provide a joke for some reason, so I said "What's the difference between a cow?"  The students thought the joke was not acceptable for a visiting professor (although there's no actual drug abuse *in* the joke), so I gave them another one: "Q. Why does the elephant wear red sneakers?  A. Because his blue ones are in the dryer!"  A student asked why such jokes tend to mention an elephant.  I guessed that the elephant class of jokes was very old and predated the discovery of Tyrannosaurex Rex, which would have been used instead if available.  Boy was I wrong!
