Realizing the time for action is long past.... do not hit; push him to the floor, preferably by flipping him over a table. Say you tripped and bumped into him. If you are good, perhaps you can "drop" a chair onto him as you rush to help him up.
btw, I have never seen someone impugn another's intelligence on the internet without misspelling something. In fact, I have no doubt that even though I am not specifically attacking a single person, I have made at least one grievous grammatical error.
EDIT: I knew it.
