Truth be told, if I ran across the young man in the pictures above on the streets of Los Angeles, I would probably run away from him, because he looks like he might be on his way to kill someone with his bare hands, for fun.
Except OH WAIT.
That's no killer. That's just Jake Gyllenhaal exhibiting his trademark questionable fashion taste as he takes his mom to lunch. (This is part of the reason I have such a difficult time believing it when he plays a badass in movies.)
