Pants-less Proof

HAHAHA! At long last, I have definitive proof that the original Robin costume did in fact involve no-pants rather than flesh colored tights as some would have you believe. How do I know this? Well, in this flashback scene from Teen Titans East, Dick forgot to shave before he went out superheroing.
Awesome. Kinda weird that it took Batman two Robins to figure out he should probably give them pants. Tim Drake was the lucky one.

I found this image on the Shirtless Superheroes blog. Plenty of beefcake, if that's your taste.
