Whatever Floats Your Boat
Two Jews, Morty and Saul, are out one afternoon on a lake when their boat starts sinking. Saul says to Morty, "So listen, Morty, you know I don't swim so well."
Morty remembers how to carry another swimmer from his lifeguard class when he was just a kid, so he begins tugging Saul toward shore. After ten minutes, he begins to tire.
Finally about 100 feet from shore, Morty asks Saul, "So Saul, do you suppose you could float alone?"
Saul replies, "Morty, this is a heck of a time to be asking for money!"
