Something like 10 years ago I found a Kris Kross (sp?) CD at my friends house so I took a lighter to it, then got mad that it wasn't bursting into flames so I cut it into confetti with a pair of scissors. He was on the phone at the time and I think he got mad for about 8 seconds, but then realized my cause was just.
I had a Dimmu Borgir VHS, the making of uhhhh, that one with the blindfolded broad on the cover. My friend said "what's this?" and I said "some shit I'll never watch" so he ripped out the tape. I yelled at him because I could've made $2 on eGay for it.
