Hiya! Captain Obvious here!
I was just in the neighborhood and wanted to pass along something important to you. You look busy so I won't take up much of your time.
So just turn your head to either side and kind of look up out of the corner of your eye. That's it! Now see that person standing on your neck? That's your boss. Got it? No, you don't need to nod "yes", because I know you can't. For I AM CAPTAIN OBVIOUS!!!
And now I am on my way! And I know that because your boss is giving me the stank eye. See ya!
