I sat in a laundry basket that was placed on the mat that your computer chair goes on(ya know so it rolls on the carpet better) and rode that bitch down a staircase. The mat was turned upside down so the spikes would slow me down. best part is when I got to the bottom and crashed I slid my forearms across the mat spikes tearing open my flesh and bleeding like hell. I was wearing a hockey helmet backwards too so I couldn't see.
I learned my lesson after the first time though, and only did it like 3 more times. Still have scars from it. You might say I had had a drink or 2. Had it on video on my old cell phone. Shit was funny as hell. My gf at the time didn't think so when I showed it to her tho.
