The newest jokes these days are French Jokes! 
One can make a case that the oldest joke we have any sort of record of is the “As I was going to St. Ives” joke. There is indirect evidence that it was known in ancient Egypt.

Although he lived considerably after the early days of ancient Egypt and Babylon, Timon of Athens, a famous misanthrope, may also be of interest.
Plutarch recorded that Timon said he was so broke that the only hot meal he could afford was a bowl of steam. Woody Allen used a variation on this in Take the Money and Run. Timon once spoke before the senate in Athens and announced he was about to chop down a tree on his property, so if anyone wanted to hang himself they had better hurry. Timon’s epitaph translated as something like this: “Go and revile me. But anyway, just go…”
“Adam caught Eve by the furbelow,
