What is the craziest dare you can think of? I would dare someone to light a bag of poo on fire on a crabby old person's front door. (Did that in Billy Madison)
Eat all the wasabi given to you with sushi, with no food or drink to go with it.
That's not much :P Maybe a teaspoon or a tablespoon (whichever is bigger) would be given to me. It would make my nose feel weird and my eyes would water...
People still do dares? xP I thought that was old stuff, from primary school, you know. Empty a tube of toothpaste down your boxers, always a good one, might require you to carry toothpaste around.
in like 7th grade or so (cant remember) i was dared to run down the main hall in my school.....nude. there was no way i could do it, but i did think about it. never happened though.
