"Oh, you lying bastard!" you yell at the top of your lungs. "How DARE you stand me up like this! So, where's the tart that you've stood me up for, eh? I thought I was the only one you were cheating with. I've got a mind to phone your wife you deceitful little worm!"

You feel a naughty sense of glee at the look of horror and disbelief on your boss' face.
