A motorist, lost in the middle of the countryside, asked a local the way to Littlemorehampton. "Easy m'dear, take the little road on the right until you come to Humbert's farm."
"But I don't know which farm that is."
"Easy m'dear. It's right on the corner of the road that goes to Littlemorehampton."

A customer in a shoe-shop heaved a sigh of relief: "At last, a pair that fits me."
"Not surprising," replied the weary salesman. "They're the ones you came in wearing, sir."

In the public house, an unmasked husband sighed to his friend: "When I think that some inventor spent months, years even, developing a lie detector! All they had to do was meet my wife."
