A very shy man had the embarrassing task of returning a pair of underpants to the shop and being served by a pretty young girl. “What’s wrong with them, Sir?” she asked.

“They’re, they’re … er, unsatisfactory,” he said, blushing madly.

“Can you tell me why?”

The man was lost for words but as he was looking wildly around for inspiration, an idea came to him. “Do you know the old Grand Hotel on Union Street?” “Yes.”

“And do you know the ballroom underneath?” “But there is no ballroom underneath.”

“Exactly!” exclaimed the man, “and that’s just what’s wrong with these underpants.”
