Dick Grayson simply had the best ass in the DCU. Even the most right-wing anti-gay men have looked at the Pre-Reboot ass of Dick Grayson and said, "Man, that is just perfect." You see, Dick's ass looks like an ass the is both muscular but not too muscular. It is both an ass that looks like you could sink your fingers into his cheeks, but also bounce coins off of it if you wanted. With Dick's levels of athleticism and strength I bet he could also snap a pencil in half with those cheeks of his if he wanted to.
You can't tell me there aren't some homos working at DC Comics! :D
