Niles and Daphne
In the 'First Date' episode where Niles and Daphne have dinner at the end (after Phyllis is scared off by Frasier), Niles could have said, "Daphne, when my divorce is finalized, and if you are still unattached, perhaps we could have an actual dinner date...". This would only be done after he had a few glasses of wine, of course.
I'm feeling my confidence return, I just need a few more minutes alone, and I'll be able to tell her everything.
