Over the Fence

A man is getting into the shower just as his wife is finishing up her shower, when the doorbell rings.

The wife wraps herself in a towel and goes downstairs to answer it.
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, she drops the towel and stands naked.

After a few seconds, Bob hands her £800 and leaves.
She than wraps herself back in the towel and goes back upstairs.

When she gets back, 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?"
