I posted on GinNs blog...

Well... It only seems right that I should post something on my own dead-ish blog since I posted something on Ginny's. Question is: what should I post?
So. Since I don't want to post anything terribly boring(that would be uncharacteristic) I have decided to post a literal thinking puzzle.

A man walked into a bar, and immediately was knocked unconscious. Why?

Okay... and for anyone who may be tempted to ask a stupid question, here's a hint: I did not make any spelling mistakes.
