the only time i can think of, was when i got caught by my parents once when i was younger, and i had to break it in the driveway in front of my dad, so I threw it down... other than that not really. There was one that I accidently dropped and the mouthpiece got fucked up so I tossed the rest of it in the air and watched it shatter outside, but that was only cause it was already busted. It scattered everywhere, it was kinda cool.
