Think it's hard to convince someone to slap themselves as hard as possible in the face?
Ha! Wrong! You can just go to Make A Dare, post a challenge you want people to try, and then sit back and wait for idiots to upload videos of themselves doing things you are obviously too big of a wuss to do yourself.
Guys, I hate to let the cat out of the bag, but getting on the Internet is not that tough. In fact, anyone can upload a video to the web for pretty much any reason whatsoever. You don't have to hit yourself in the face anymore! You're free!
