Triangle Dude is soooo hardcore.
If he were a planet, he'd be a super dense planet... because then he'd have a harder core.
When life gives him lemons - he throws them back at life's face!
HE'S SO HARDCORE HE EATS NOTHING FOR BREAKFAST!
Anyways, here's the comic where Triangle Dude is "So Hardcore."
On a related note - guitar smashing was first done by Peter Townshend from "The Who." I've also read that there may have been a few other lesser known instances where a guitarist smashed their guitar, but I believe Peter is the first one to really get it known. Interestingly Peter may have also smashed the first guitar by accident... but the crowd loved it and so... he kept doing it lol.
Guess what... Wikipedia even has an entry on "instrument destruction"... wow.
