Tzedaka

A Rabbi and a Priest are sitting on a bench in front of church. They have bowls in front of them to collect money and as the parishioners exit the church they leave some change and bills for the Priest and give the Rabbi dirty looks.

After some time one of the parishioners takes pity on the Rabbi and walks up to him and says "Rabbi, I think you may be at the wrong venue. This is a church so the people here will only give money to the priest".
Upon hearing this the rabbi then turns to the priest sitting next to him and says "Moish, this guy's trying to tell us how to do business".
