Soupy Sales used this at a local comedy club (as best as I can
remember it):

A young girl is sitting in a barber shop with her mother, eating
a twinkie, and anxiously awaiting her first haircut. When her
turn comes, she brings her twinkie with her to the chair, and
the barber covers her. Soon, she pulls the twinkie out for a
bite.

Youre getting hair on your twinkie, the barber playfully warns.

Yes, I know, replies the girl. And Im getting boobs, too.
