To strip them senseless... unable to hear rhythm or feel bass...
Take back every track you've gotten stuck in their feeble little head?
Revoke every intellectual property you've loaned, get Lou Reed to spit in their face, Bowie to give a good fucking slap, and Iggy to just turn around and walk away...
Send Hesse back from Nirvana to inform that the next life will be spent as a tick on the back of an opening acts' drummer's cat...
Then, after the fact, hang the Magritte prints again, thanking something silly in the way that you never hung them up in front of the slug; its been saved from the taint, and can be enjoyed for what it is... mine.
Take the opportunity to blame the dust on your guitar on them. Its well-deserved, and you and your guitar will reconcile much easier with a common enemy.
Just one thing: do not start smoking again.
