As retold by Bruce Lowitt

Chaim Yankel needs his tallis dry-cleaned. On Monday he takes it to Wing Fong,  the town's best dry-cleaner, and tells him he'll need it by Thursday afternoon.

"Fine." the dry cleaner says.

On Thursday, Yankel returns. He gets his tallis and a bill for twenty-five dollars.

"Twenty-five dollars to dry-clean one tallis?" Yankel exclaims.

"Oh, no, no!" "Wing Fong says. "Five dollars to clean the tallis. Twenty dollars to take out all those knots!"
