Seriously though, I am not a huge baseball fan. I only follow the Phils in the post season. But I know enough to know that Manny even had a ^^^^ covered helmet when he played for the Sox. So what the ^^^^ is up with that? Seriously I always wanted to know why he shat on his helmet.
I know towards the end of his time in Boston, he developed a habbit of knocking it off his head as he rounded bases so I imagine it's just repeated blows to the ground doing it.
