So the Zen master steps up to the hot dog stand 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 hot dog vendor puts
 the bill in the cash register and closes the drawer.

 "Where's my change?" asks the Zen master.

 And the hot dog vendor responds, "Change must come from within."
