Since the dawn of time, men and women have been attempting to understand each other. To most men, women are a mystery.

1. Gives_Wrong_Answer has some misconceptions on the mechanics of tampons. Sorry, guys. There's nothing cool or explosive about them.

I had no clue that the string on the bottom of a tampon was to pull it out when you wanted to change it. I thought for sure that a girl stuck the tampon in, pulled the string, and it expanded like a mini explosive. Kind of like a rip cord and a parachute. I was clearly wrong.
