A man is getting into the shower

A man is getting into the shower just as his wife is
finishing up her shower, when the doorbell rings.
The wife quickly wraps herself in a towel and runs
downstairs.
When she opens the door, there stands Bob, the
next-door neighbour.
Before she says a word, Bob says, "I"ll give you $
800 to drop that towel."
After thinking that she has a chance earning $800
within a minute, the woman drops her towel and
stands naked in front of Bob, aftera few seconds,
Bob hands her $800 and leaves.
The woman wraps back up in the towel andgoes
back upstairs.
When she gets to the bathroom, her husband
asks, "Who was that?"
"It was Bob the next door neighbour," she replies.
"Great," the husband says, "Did he say anything
about the $800 he owes me?"
