A new car on Pyramid's Christmas episodes as a Mystery 7 prize? Wow!
That's one Christmas gift you can't pass up on!
That's just as good as winning $1100 on a 7-11, $5K for the tie-breaker, and $10K/$25K.
Also, after a little thinking, I'll add Beat The Clock to the list, because, as I recall, from the "12 Games and "Snow Days" Marathons, they did a special Christmas episode of the Monty Hall BTC from 1979. As to the other versions, I don't know.
I'll also add the rest of the "12 Games" shows to the list: Super Password, Tattletales, To Tell The Truth, The Dating Game, and Body Language.
