WTF? Ethan Embry Edition

I just caught the last half of this show, Numb3rs, on CBS... Ethan Embry was a guest star and damn, did that boy get buff. When did that happen? I'm so used to seeing him skinny & kinda dorky (think Empire Records) that I didn't even believe it was him. It's like when Anthony Michael Hall showed up in Edward Scissorhands... crazy.
