Lame.

"There was a brief moment when it looked like Brock might smash his guitar on the stage (but instead, he put it on the ground after tossing it around from its strap)."

Either smash the thing or don't take it off at all. You can't go halfway with these things. Can you imagine Townshend in 1966 making ready to smash the guitar, then carefully putting it on the floor? Or how about the front cover of 'London Calling,' Paul Simonon placing his guitar 'on the ground.' What an iconic image that would've been.
