What happens when you stick a firecracker up a persons butt?

Go do it to yourself and find out for yourself. Do it in a hospital parking lot. Notify the press before hand.

Excruciating pain and a visit to the emergency room. Possible legs blown off if the firecracker was positioned right and it was a strong enough one. You could also be arrested or at least sued for a lot of money. Of course, I may not be entirely right. You should try it out on yourself so you can tell us what it REALLY feels like.

Like others have already said-why don't you try it and then let everyone know the effect it had on you. Be sure to make a tape and send it to... Funny Home Videos...Are You for Real???

boom happens. *makes boom sounds* lol =P

I say you should stick a Stink Bomb up there....

Depends. Anywhere from low degree burns to possible rupture of the colon..... Any residues of the firecracker might be toxic, and would easily go into your bloodstream through the rectum.

You won't know til you try it yourself so, please be my guest.

lol i would guess a boat load of pain and a shredded anus for the other person, quite possible **** everywhere and you would be absolutly laughing your *** off. I say do it. hahaha

thats just sill
