Hahaha... since this is an odd topic anyway...
A few years ago me and this other kid in one of my classes blew up a cd or two. It was pretty fudging funny. Everyone turns and looks at you from the HUGE cracking/exploding noise, and sees tons of little glitter pieces of CD confetti floating all around you. It's kind of hard to pass the blame off
. It was a bit of a blow off class with a ton of people in it, so the setting was just right. I'm really not the class-clown-hungry-for-attention-kind-of-guy, but being bored as hell and then exploding a CD-R with your bare hands and seeing everyone turn around to see the aftermath is pretty damn funny
. Good thing the teacher loved us
