Nothing to write about -- no joke!

It really is the dog days of summer, and other than the small matter of the disengagement, there is very little of interest going on. So I guess it's perfect timing for SIW to launch a search for the world's best Jewish joke. And not just any search -- he writes in an email that he wants a 'serious and in-depth' discussion on the subject! LOL.
In any case, I can't tell jokes for the life of me, but here's one golden oldie I saw in this week's Forward to kick things off:

Two Jews are shipwrecked on a desert island in the middle of nowhere. One is frantic, but the other reassures him: "There's nothing to worry about. The UJA can find us anywhere!"

Ok, ok. Think you can do better? Have us rolling in the aisles in the comments.
