Barker: (Explaining the Bonus Game) "I hope you get the prize beside the window that says "bonus"... that's B-O-U-N-S" (realizes his mistake) I just wanted to see if you were paying attention... that's right.... the window that says B-O-U-N-S..."
Barker: (after a showcase where Dian pops out from a movie screen, wearing a swimsuit) "I was just thinking... if I got a screen like that... could I get a blonde to come out from it?" (I'm sure Barker would regret saying this many years later)
Barker: (after being kissed many times by a female contestant, for members of her family) "I only wish you had a larger family!"
Bill Cullen, on Blockbusters: "What K does Miss Piggy love"...(Leland buzzes in) KERMIT?... I mean... Leland!"
(On Password Plus, the Password was "Shore", and Elaine Joyce was one of the guests)
Allen: (to Elaine) "Second clue, Dinah... (Elaine does a take) uh, Elaine (obvious edit) Ok! We'll put "shore" on the board because Ludden has a big mouth!"
Not really a HOST slip up... but on All New LMAD, Monty was asking questions to a couple, for a quickie deal at the end of the show.
Monty: (whispers to the woman, woman whispers answer in Monty's ear. then Monty asks the husband) What is her birthday?
Husband: March 14 (wife rolls his eyes)
Wife: That's YOUR birthday
Husband: OH! I thought you wanted MINE.
Monty: I'm asking for YOUR birthday! You KNOW your birthday! (does a Jack Benny stance) Ok, I'll give you another chance, without looking, what color are her eyes?
Husband: Blue
Monty: Let's see (looks at her eyes) No, they're GREEN! They're as green as green can be.
