A slightly dim-witted blonde goes to a drugstore to buy a pack of condoms. The 3-pack is marked $1.00, but when her purchase is rung up by the cashier, the register shows $1.06. "I thought these condoms are only $1.00," she exclaimed to the cashier. "Oh no, ma'am," he said, "the price is $1.06, including the tax." "Tacks?" she asked. "Why, I thought you just roll them on!"
