Crime: Caused me to have a hernia laughing at his musical stand-up routine.
M.O.: Sitting at a keyboard, he encouraged audience participation in the song "If you're happy and you know it clap your hands" before violently subverting the lyrics. ("IT'S 'STOMP YOUR FEET MOTHERF*****S!'). Also launched into a sexually explicit love song.
Last sighted: Possibly Melbourne International Comedy festival. Worldwide no doubt.
This man must be brought to justice. Do not attempt to apprehend, but please post sightings here. Thank you.
