Fettucine!...

(said in rasply exclamation a la Kirstie Alley in a Jenny Craig ad)

For some reason this has become the new catch phrase around the house between me and my kids.
It is all encompassing, multipurpose and can be used in greeting, when one is confused, or amused at something, or just for the sheer experience of saying it for no reason at all.
If one of us yells it out someone else inevitiably answers or laughs. (or both)

But ya gotta say it like Kirstie Alley.

Fetah CHEE NEY!!
