The perils of yuletide singing

I was chatting for a minute with a co-worker, who's going to the airport straight after work. So I thought, since I'm known for singing at the drop of a hat but she's never heard me before, that I'd do a few notes for her. It went something like this:

Oh there's no place like home, for the holi -- AHHH!

The "AHHH!" was because I started to focus so much on my singing that I nearly dropped my steaming cup of Earl Grey. We both laughed, but for different reasons. It was not the first singing impression I wanted to make. Still, I must admit it was funny.
