Quote context

- Your own personal proof of this is Pepsodent's clean-mouth taste for hours.

- So try new Pepsodent White, or if you prefer chlorophyll, Pepsodent Chlorophyll. You'll like.

- Pepsodent's new flavor! Pepsodent's new flavor! Wow! Pepsodent's new flavor! And a clean-mouth taste for hours!

- And now, here's Mr. Cummings with our stars.

- And here they are, after two out-of-this-world performances, Michael Rennie and Jean Peters.

- Mike, have you ever seen any U.M.O.'s?

- What's a U.M.O.?

- An Unidentifiable Moving Object.

- Yes, I saw several U.M.O.'s years ago in London.

- You mean during the war?

- No, when I was a very young actor, but the flying objects were later identified as ripe tomatoes and eggs and cauliflower.

- Well, how about you, Jean? Seen any flying saucers?
