I dont know if this would happen to the item if in game, but the version on mods.tf glitches sometimes, (I think its when he opens mouth or changes facial position, like in taunts and in the character select screen) and the glitch is just that the bottom of his goatee becomes invisible and instead of a goatee you see a handlebar moustache (because thats what the goatee looks like without the bottom/chin hair, a handlebar moustache)
