At lunch time, a recovering alcoholic decides to pay a visit to his new sponsee, who sells hot dogs from a push cart. "Make me one with everything," says the sponsor.
The sponsee fixes up a hot dog with all the trimmings and hands it to the sponsor, who pays with a $20 bill. The vendor puts the bill in the cash box and closes it.
"Where's my change?" asks the sponsor.
The sponsee responds, "Change must come from within."
