A Zen master visiting New York City goes up to a hot dog vendor and says, ‚€œMake me one with everything.‚€Ě
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. ‚€œExcuse me, but where‚€™s my change?‚€Ě asks the Zen master.
The vendor responds, ‚€œChange must come from within.‚€Ě
