Zac Efron in Mike O'Donnell's gangsta getup
BTS and in costume on 17 Again...

He totally needs a copious amount of tattoos on his arms to be taken seriously in that outfit. Although, I'm not sure even that would help cause it certainly doesn't work for kfed.

Also, here's to hoping Zaccy will be at the Nick Kid's Choice Awards today. Though I'm not holding my breath since Z has apparently vanished off the face of the earth...

And yes, that is a wig... his dorky 1989 hair wig.
ETA: Megome says it isn't his 1989 wig... just his hair styled to be dorky. Source
