Borrowing!

Every time the man next door headed toward Robinson`s house, Robinson knew he was coming to borrow something. "He won`t get away with it this time," muttered Robinson to his wife. "Watch this."
"Er, I wonder if you`d be using your power-saw this morning," the neighbor began.
"Gee, I`m awfully sorry," said Robinson with a smug look, "as a matter of fact, I`ll be using it all day."
"In that case," said the neighbor, "you won`t be using your golf clubs, do you mind if I borrow them?"
