My first thought was "can't we just make an exception for these guys?" But what happens when the guy carrying the cello is wearing a turban and has shaved off all his body hair?
Ask him to sit down and play the opening bars of "She's a Grand Old Flag"
I watched The Flight That Fought Back yesterday, and they showed the terrorists shaving their arms in the bathroom in preparation for their big day. What is with that? Did Mohammed hate body hair in addition to dogs?
