What's the big deal? Yea it may be a girly thing to get done, but I think there are certain instances that a guy can get a manicure.
A. He has a very very very special occasion coming up, and will be photographed a lot and need the phalanges and nails looking top notch.
B. He has fairly nasty nails, and/or cuticles so he just plain ol' needs it done.
C. He is man model or hand model.
My reason would be A..... aaaaand Shorty would say B too, but I disagree, I thought they were more the Rugged - I work 14 hour days in the steel mill - Derek Zoolanders dad and brothers - look. But I'll tell you what, either way I got it done, and I don't even give a care what anyone thinks, because they look f-ing legit.
