A priest, a minister, and a rabbi were sitting around discussing the pigeon problem. Each house of worship was being over run with pigeons on the roofs. The minister said "I tried to shoot them off, but they'd just circle around and come back. The only damage it did was to put holes in my roof."
The rabbi said, "I tried to smoke the pigeons off my roof, but all that happened was the roof caught fire."
The priest then told the others that he managed to get rid of the birds. The others were amazed and asked what his secret was. "Well," he said, "I just baptized them, confirmed them, and I haven't seen them since."
