In the episode of "Wings" where Frasier and Lilith guest starred, Frasier kept talking about his babysitter, Dagmirer (Not sure if I spelled it right). Apparently she was attractive and young.

My question is, was she ever seen or refered to on "Cheers" or was she just made up for "Wings"?

I think she might have been referred to once on Cheers. Remember the episode where Sam and Rebecca were debating whether or not they'd be good parents. They offered to take care of Frederick, and Lilith said something about it being a good change from "That big bundle of breasts that Frasier thinks is God's gift to babysitting"?
I think that might be it...

Thank you for responding. That sounds right.
