For Stan's birthday, his wife wanted to surprise him when
he came home from work.  After some careful consideration she
decided to strip naked and wrap herself in saran wrap from her
shoulders to her ankles.

Pretty soon Stan enters his house exhausted from a tough day
at work.  He walks through the kitchen, places his lunchbox down,
and hears his wife say, "Honey!  I'm in the living room."

Rounding the corner, he spots her all wrapped up in plastic.
After a quick peek, he immediately  says,
"Leftovers again!"
