After being away on business, Tim thought it would be nice to bring his wife a little gift.

"How about some perfume?" he asked the cosmetic's clerk.

She showed him a bottle costing $50.00.

"That's a bit much," said Tim, so she returned with a smaller bottle for $30.00.

"That's still quite a bit," Tim complained.

Growing annoyed, the clerk brought out a tiny $15.00 bottle.

"What I mean," said Tim, "is I'd like to see something really cheap."

The clerk handed him a mirror.
