Shaved Leg

Throughout my life, my brother never ceases to amaze me with the randomness he has. Yesterday I went home, sat down on the couch and turned the TV on. My brother turns to me and said,"Look what I did!" He then proceeded to pull up his pant leg. At first I didn't realize what exactly he was showing me until I saw what he had done. My dearest 20 year old brother had shaved his leg, and badly too by the looks of it. I couldn't believe my eyes. I asked him why in the world he'd do such a ridiculous thing, and he replied that he thought it would be funny. My only hopes are that he didn't use my razor! So fellow peoples of the world I need your help. I need reasons, other than "I thought it would be funny", for why in the world a guy would shave his leg or legs.

P.S. My brother is planning on shaving the other, it just took him so long to shave the first that he didn't want to spend another 20 minutes shaving the other.
