A couple of older bums are relaxing on a park bench, bored out of their minds. They're not the brightest of crayons, but are known to be pretty resourceful - especially when bored.
So one of them says to the other, "What are we gonna do today?"
The other replies, "Well, how much money have you got?"
They both rummage through their pockets, emptying several days worth of lint and toothpics, managing to put together about four dollars and some change.
The first one says, "We can't do much with 4 bucks. Maybe we should just go home?"
The other, excited, replies, "Nah! Let's go buy a box of tampons!"
"Tampons? What are we gonna do with tampons?"
"Haven't you seen those TV commercials? With tampons we can run, and hike and swim, even go dancing. We need some tampons!"
