The beard itself being like Velcro, as in full of clingy barbs, not the hamburger. Lolz back at'cha. Wouldn't explain how a spoon would stick, but maybe that's just static electricity. Yeah, maybe it's a whole mix of being wirey, sticky with juices and susceptible to static cling. :P

Vergo = user of the static (electricity) DF; placing bets now.
