The pizza boy is sitting there when he returns to normal and has a
distinctly empty feeling in his body.
The party guests take him to the kitchen and have him drink pitcher
after pitcher of water until his belly sticks out as if he were 9
months pregnant with triplets.
The pizza boy was too stunned with the events to know what they were
doing but as soon as he was full Doug then types in full keg of beer
and points it at the pizza boy.
Soon there is another keg fully filled sitting in the middle of the
room.
This could go on all night they better invite over more friends. And
soon there is a full fledged party going with a permanently filled
keg.
