A pal of mine went through a rather odd period a few years ago. Grew an enormous 2-ft beard, became extremely argumentative, started railing against the west, considered becoming a muslim etc. Having nothing to do over the new year, he went to Beiruit by himself, checked into a hostel and was immediately taken for a jew by the owner, thanks to his whopping facial bush. This guy basically refused to believe he wasn't jewish, every time he saw him he'd cackle and make semi-comedic, threatening gestures at him. My mate was too scared to go out and get a razor so he basically moped around this dingy hostel for three days. Then flew home early. Sorry, I've got no idea why I'm writing this...
