Cress… I’m never getting on your bad side! 🙂
Kerry, I’d start with the “soft approach” before escalating this to all out war.
For example, remove the power cable from his speakers when he’s out and hide it somewhere different every day.
Or uninstall his sound driver. It’s not the end of the world as he can reinstall but persistence can be a b*tch.
If he asks you what happened to his power cable, just tell him “I don’t know, but I like it this way”.
Come on… I’m sure that would put a smile on your face, right? 🙂
If that doesn’t work you might have to go for Charlie’s, Rick’s or Cress’ tactics.
