Hey, I am entirely not trying to be an ass, but in situations like what just happened there, here is what I usually do:

Christoper Walken Lee (EDIT: Derp)

Something like that is what I try to do when I make a silly error, but want to showcase that I made the error, and then also accepted and made the correction.

That way, if somebody in the future, who reads only the edited version of the comment/post/thread sees it, they can understand that perhaps other comment chains based off of the initial error are not non sequiturs.

It also shows that you are humble and admit a mistake, and make a correction, which imo, are good things to showcase... as opposed to doing a 'stealth edit', which leaves no obvious signs of what the original comment was, in the comment itself.
