Some guys stockpile condoms when they're sexually active, convincing themselves they'll need to have hundreds of condoms on hand when they could easily get by with a half dozen.
Soon their bedside drawer is overflowing with safe sex products, and the time comes to thin out the "collection" before it scares away potential partners. But what's a guy to do with all those extra condoms?
He could donate them to a friend's cause, or he could do something fun with them like use them as an improvised fishing bobber, take them on a camping trip and use them to start a fire, or fill them with flour and put them to use as a stress balloon.
Just make sure you use the non-lubricated variety or those suckers are liable to go flying across the room!
