Dude. We were all in his basement like a week ago. I just happen to know the promoter, she needed to fill the spot, called me, and we were all smash drunk when we said yes, okay? Please stop yelling at me?
I've done far stranger, for far more questionable of reasons. Like the time I robbed a 7-11 at gunpoint for a pack of gum because a drunk told me he'd tell the world who I was if I didn't, and when I seemed interested in who he thought he was, he said he'd tell me if I did it. Except then he was gone when I got back, so I just returned the gum and fenced the gun and made a tidy 200 dollars.
