Bitch slap city

Was watching House and caught this promo for Glee's finale which ends in an AMAZING-ly vicious slap to the face. Blink and you'll miss it but if you're like me you'll rewind a few times (including one time in slow motion) just to behold the brilliance. I'm always impressed when a bitch slap comes off believable and this is the best I've seen on TV.  Diana Agron, if you're reading this, give yourself an Emmy.
