Two old Jews are walking past a church

A sign out front reads, "Convert to Catholicism, get $20."

The first Jew keeps walking, but soon notices his friend has stopped to take a closer look at the sign.

"You're not actually thinking about doing that, are you?" he asks his friend.

The second Jew turns back and says, "I don't know, twenty dollars is twenty dollars." He goes inside the Church, and comes back out about thirty minutes later.

"So," says the first Jew, "did you get the twenty dollars?"

The second Jew turns to his friend and says, "Oy, is that all you people think about?"
