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 for a moment, the woman drops her towel and
stands naked in front of Bob. After a few seconds, Bob
hands her £800 and leaves.  The woman wraps back up in
the towel and goes 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?"
