my husband's frantic call for help

I was preparing food for the baby shower I threw yesterday in honor of my dearest friend, who is expecting twins! Then I heard my husband scream for me, and the rest is history:

Greg: Deb, get in here now!

Me: WHAT? What is it?

Greg: Ohhhh, this isn't good. This isn't good at all.

Me, running: What? What happened?

Greg: I was dusting the piano.

Me: Yeah, and?

Greg: And I sprayed it with RAID.
