Bunty’s Dare

Ethel and Bunty were getting just a little bored in the senior citizens’ home, when Bunty had an idea. “I bet you $100 that you won’t streak round the garden, Ethel.”
“You have got a bet,” replies Ethel, so she disrobes and sets off round the garden.
Tom and Bob were enjoying a relaxing time in the garden when Ethel went past.
Bob says, “Wasn’t that Ethel that went by?”
Tom replies, “Yes, I do believe it was.”
“What was she wearing then?”
“I don’t know,” said Tom, “but it surely needed ironing.”
