Season 8, Episode 20: "The Millennium"

Oh, Mrs. Hamilton, this is a very bad time.

I've got Valerie on the other line. Just a second.

- Hello. - That's her, isn't it?

- Well.... - I don't want you on her speed dial.

She knows about the speed dial. You gotta get me off this thing.

I won't until she puts me back on hers.

She wants to be back on yours.

- Fine. But only if you're off hers. - Hang on.
