I was in the middle of recording today, and my brother barged into the room, talking to me and rummaging around, trying to find something. He even bumped into me while trying to walk behind the throne! I managed to hit him behind my back a couple of times, and not totally ruin the session, haha. You can see the video of it here: http://www.youtube.com/watch?v=btx2SDBkY3s
So this inspired me to start this thread, what humorous/horrible/strange things have happened to you while you were either playing out or recording, and how did you (hopefully ;D) escape gracefully from the situation?
