Mrs. Cohen came home from her Sisterhood meeting at the synagogue.

She was very excited, and explained to her husband that the guest at the meeting had been a wonderful hypnotist.
Mr. Cohen then mentioned that attendance was down at the Saturday services. Maybe they should hire the hypnotist to bring in a crowd. He talked it over with the rabbi, who thought it was a terrific idea.
After lots of publicizing, the synagogue was filled for the Sabbath service.
The hypnotist withdrew a pocket watch.
As the crowd observed, mesmerized, the hypnotist began, "Vatch the vatch. Vatch the vatch. Vatch the vatch."
The congregants carefully observed, their eyes following the sway of the watch.
"Vatch the vatch," the hypnotist continued.
Then, accidentally, the watch fell out of his hand.
"Crap!" he exclaimed!
It took them three weeks to clean up the synagogue.
