### Toilet Paper

A little old lady goes into the store to do some shopping. She is bewildered over the large selection of toilet paper.

"Pardon me, sir," she says to the store manager, "but can you explain the differences in all these toilet papers?"

"Well," he replies pointing out one brand, "this is as soft as a baby's kiss. It's $1.50 per roll."

He grabs another and says, "This is nice and soft as a bunny, strong but gentle, and it's $1.00 a roll."

Pointing to the bottom shelf he tells her, "We call that our No Name brand, and it's 20 cents per roll."

"Give me the No Name," she says.
