A little bit o' dialogue from Jack's guest appearance on George & Gracie's TV show for the occasion (this is from memory, sorry if it's not exact!):
Jack and Gracie are on a train from San Francisco to L.A.
Jack: Gracie, you're Irish, right?
Gracie: Yes, that's right!
Jack: You know, Dennis Day is Irish too.
Gracie: Oh, I know it.
Jack: Well, I was just thinking they had better come up with another George Bernard Shaw pretty soon...
