I think I just figured out Nathan Drake's TRUE origins.....(Spoilers!!!)

No, carnies are just dipshit methheads who swindle money from marks with their crooked ball games. Now, it has been made pretty clear that Drake was previously raped by a clown (possibly more than one), but to assume that any of this means he was actually in the circus is a bridge too far.

that is a terrifying thought but possible lol. Clowns would of had unlimited access to him if he lived with a Circus >_>......... lets just say one was mean to him when he was a small child and that is it...for my peace of mind lol.

But seriously, think about my points and say he doesn't sound like someone with training in Acrobatics? I mean he was either a gymnast or a trapeze artist/ or maybe the escape artist.

Drake also makes the comment that he taught Sully and Dante(U:GA) how to scale stuff like him, hinting at he knew how before he even met Sully (made more apparent at his skills as a child in U3). That means he was 15 or younger with that kind of skill, no way he just fell upon such abilities with so few years on earth.
