[gestures towards second guy] "his head is going up your ass... [to fourth guy] ...and you drew the short stick, 'cause your head is goin' up my ass."
"You didn't." Red after Ray cuts his OTHER hand off...
When Hancock accidentally bounces a basketball over the fence of the prison he's in, he simply leaps over the wall to fetch it. Once he holds it, he stops and thinks that he could just walk away, that he doesn't have to do anything he doesn't want to. But he leaps back over the fence anyway.
It's after this that some of the criminals actually start looking up to Hancock - he still put them in there, but he's more one of them.
However the best moment is easily when Hancock single-handedly takes down a team of criminals robbing a major bank, who are armed with grenades, heavy machine-guns and RPGs. He just swoops in and takes them all out, even deflecting a missile with his hand.
During the finale a powered down Hancock faces a small team of heavily armed mooks out to kill him. Simply put, Hancock is not the other guy. He's the guy who will literally shove your head up your ass, because he can.
Hancock spraying the All-Heart logo on the moon. Ain't nobody gonna say that the All-Heart logo isn't good publicity now...
