Returning the Trick

One Halloween, a trick-or-treater came to a woman's door dressed as
"Rocky" in boxing gloves and satin shorts. Shortly after she gave
him some goodies, he returned for more.

"Aren't you the same 'Rocky' who left my doorstep several minutes
ago?" she asked.

"No," he replied, "I'm 'Rocky II'. I'll be back three more times."
