Boss walks into the studio: "Thanks."

Me, hearing the obvious sarcasm in her voice: "Um... for what?"

Boss: "For playing the Macarena this morning."

Me: "Um... you're welcome?"

Boss: "Thanks to you, I spent 15 minutes in my office trying to remember how to do that damn dance."

She then stormed out of the studio while I pondered playing The Locomotion or The Time Warp next.
