- I also did a special called "Dick Van Dyke and the Other Woman," where I brought Mary on and just let her do everything she wanted to do and we did some great stuff together.

She was, she had attempted to do a Broadway show that was a musical version of "Breakfast at Tiffany's."

It was doomed.

It was doomed.

But we thought it would be fun to do a special reuniting, the two of them.

- I've worked with a lot of wonderful actresses, but you know, after doing a series together for five years, well, Mary just kind of holds a special place in my heart.

- With his wife's approval.

- Yes, ma'am, right.

(audience laughing) Normally that phrase, the other woman, implies a relationship between two people, which might be considered unsavory.

- Yeah.

- But of course, a relationship between Mary and myself is of course completely savory.

- Completely.

Actually, when we were doing the series, people thought we were married.

- Oh boy.

So much so that I often had trouble checking into a hotel with my real wife, Margie.

- And I had trouble checking into a hotel with my real husband, Grant.

- And Margie and Grant had trouble checking in anywhere.

(audience laughing) - They gave me a wonderful opportunity to sing and dance and clown and do everything that I felt comfortable doing.

And Dick stood by applauding my every move.

It was very successful.

And CBS noted how successful it was, how comfortable I seemed being in the spotlight.

And they asked me if I wanted to do my own show, to which I said yes.
