Garret Claridge (poopooGarret)

He's one of the Big Six of YouTube destroyers, so I'm sure you all know who he is, but I figured I'd give a mention here since he's the smaller of the Big Six. Here's a listing of who in my opinion are the Big Six.

Blendtec - Will It Blend?
JPizzle1122 (Jogwheel) - Is It A Good Idea To Microwave This? Plus they have a few non-microwave destruction videos such as where they dropped computers off of a bridge.
dOvetastic - Mostly known for dOvetastic Microwave Theatre but has probably the biggest variety of things including high voltage cooking, ironing, speaker blowouts, toaster oven cooking, food processing, sawing through, smashing, and so many others.
BLHProductions - Mostly known for "What Happens When You Microwave This?" but they also have a few other destruction videos.
Smash Doctor - Perhaps the best known smash artist out there and IMO the best
Garret Claridge (poopooGarret) - Has a mix of microwaving videos, smash videos, and speaker blowouts. Probably the best speaker blowout show on the web.

Here's his channel: https://www.youtube.com/user/poopooGarret

And here's one of his better known speaker blowout videos.

Gotta' love poopoogarret. I discovered him years ago way, way before he changed his username.

Have you seen "Smashing Stuff" by Randumb Productions?

Not sure. I'll have to check it out, though

That was more amusing than it should be to watch speakers blow themselves out.
