Zen and How

A Zen master visiting New York City goes up to a hot dog vendor and says, "Make me one with everything."

The hot dog vendor fixes a hot dog and hands it to the Zen master, who pays with a $20 bill.

The vendor puts the bill in the cashbox and closes it. "Excuse me, but where’s my change?" asks the Zen master.

The vendor responds, "Change must come from within."
