The Jewish guy says "The Romans did it."
The Captain says, "Right, you're admitted."
The Italian guy goes in next. The Captain asks him the same thing. "We have to ask you one question first before you're admitted to the Police Academy. Who killed Jesus?" The Italian guy says "The Romans did it." The Captain says, "Right, you're admitted."
