This punches only? Kicks I have more stories, but with punches probably a left haymaker(I'm southpaw) that ko'ed a guy.

Been hit with? I've been boxing and kick-boxing for quite a while, and I've haven't really been hit cleany by a punch thats really hurt me. However one time I came back to kick-boxing after boxing and I ducked a combination only to have a kick land and when I straigthened up I was a little off balance.
