ewww man . You still got the helmet? Or you thrown it away because you couldn't get rid of the smell?
The stupidest thing I've done is play my X box for an entire weekend. Constantly. I completed Halo 1 and 2, DOA 3 and Ultimate, and all the games on the Sonic Mega Collection.
It might not sound that stupid, but when you couple that with hardly any food or drink because I kept forgetting to get something, you get major dehydration, malnutrition, sleep deprivation, slight arthritis in your fingers, and your eyes feel like someone has gone all over them with Sandpaper.
That's my stupidest thing I've done becuase I actually chose to do that.
Never again...
