Umm. How about just leaving the bar? Or taking a 5 minute break. Or calling security over?
What are we...meatheads?....neanderthals...Patrick Swayze?? Is committing a felony ADW on some drunken idiot by hitting him in the head with a telecaster really that enjoyable for you guys? Just a question.
When someone cuts in line at the grocery store do you pick up a can of soup and hit them in the head? So why is it so acceptable to hit someone for climbing up on a stage? We teach our children to not behave this way.
What if it was a drunk woman jumping up on stage? Are you gonna strike her down? Pop her in the head with end of your guitar? C'mon folks. We all know you ain't gonna do that. What if she was really really hot with boobies bouncin around and she jumps up on the mic and starts singing...you gonna stab her with your headstock? hahaha I think not! But if it's some sweaty fat guy you're going to ADW him? There's whole lot of FAIL going on there.
And don't get me wrong, I've gotten pretty pissed off at some of these drunks. I had a drunk dancing in front of me once and he hit the mic stand which sent the mic into my face...I was very pissed. But I wasn't about to go assault the moron over it. I stopped the set and got on the mic and said "SHOW OVER unless this MF'ER IS ESCORTED OUT OF HERE" Some unrelated people carried him out the door. Mission accomplished
Anyway, to answer your question...I'd use a BC Rich Warlock if I had one.
