How NOT to get promoted

So yesterday I had a bit of time at work and thought I would email this really funny joke to a co-worker of mine. I got it all ready and hit the send button with out checking the To: line. This is unfortunate. Instead of sending it to the co-worker intended, I sent it to the corporate accountant with the same first name. The picture was of me doing something silly as a child.

Original Email: HA! How cute am I?

Response from Corporate: Yes, you are very cute... but who are you? I think you've sent this to the wrong person...

My Reply To Corporate: Um.. yes. Very cute.. not so smart! Sorry about that!

Forward to correct recipient: I hope you find this really funny, because it's going to get me fired.

Thank god it wasn't something really inappropriate. With all the knowledge about how NOT to abuse my work internet privliges (I think I even had to sign a memo), you'd think I would know better. And I quote: Cute.. but not so smart!
