He's a Jehova's Witness.. I guess he uses the tongue to open locks and stuff..
I can see him stand in doorways, in one hand a bible, in the other a chain, the hair all messy, the eyes staring wild while he shouts:
REPENT!! REPENT SINNERS! LISTEN TO CHILDREN OF BODOM AND REPENT YOUR SINS!!! AAAAAARRRGGHHHH!
