I remember a while back, one of the gossip sites was giving Beyonce Knowles a bunch of crap for posing in numerous photos with her arms up behind her head. She always looks great, so I guess it was a very slow news week or something to that effect.  Anyhow, here's a batch of covers with people also showing off their pits-- some au naturel, some shorn, some covered up.

BTW, Nugent is the king of said pose; there's almost always at least one pic of him doing it on his album covers or inner sleeve.
