More fiction fun and odd words

I was just watching my DVR-saved episodes of Sanctuary on the SyFy network. Someone in the story made reference to needing House for a medical question. I just get a kick out of writers who don't take themselves too seriously. Two very different programs on different networks makes it even more fun.

On another blog topic, I saw a business that was having a Pre-Grand Opening. That was a new idea to me. Is it just a little opening, with a grand one to come later? What does that mean?
