he's not derranged... he's funny. that just like him to me, and not out of character at all. his sense of humor is just a little weird. but is naming a snake really that weird..? i would have probably done the same.. barney was probably the first thing that came to mind. nothing derranged about that.
lighten up.

p.s. - i love him. always have. he's not in the tabloids nearly as much as other young actors/actresses... and he's had a dui... so what? so have two people in my family.. and we are pretty down to earth, living "comfortably", kind of people.
