World: meet Arron Crascall. He's British, yet freaking hilarious.

This video made me laugh out loud. "LOL," as the kids say nowadays (I think, right?). If you don't do this when your favorite song comes on (...jam? When your Jam comes on?), then I bet you want to.

I do, but most people don't appreciate me squawking Slayer in the grocery store. Not everybody has such impeccable tastes in music!

What song do you like to belt out when it comes on?
