My Uncle Moe used to work at a pharmacy, mainly in sales, for over twenty years and he told me the other day that a teenager came in one day some time ago and asked him, "Sir, how much for a box of those condoms?"
My Uncle told him, "Let's see. This box here would be $4.00."
"Oh, let me check here..."
"Actually with tax, they would be $4.24 cents."
"Tacks? So that's how you keep them on?"
