How about the following?
There's a priest, a minister and a rabbi out playing golf and trying to decide how much to give to charity.
So the priest says, we'll draw a circle on the ground, we'll throw the money way up in the air and whatever lands inside the circle, we give to charity.
The minister says "no", we'll draw a circle on the ground, throw the money way up in the air and whatever lands outside, that's what we give to charity.
The rabbi says "no, no, no", we'll throw the money way up in the air and whatever God wants, He keeps.
