I'll Bet is an American game show that ran on NBC from March 29 to September 24, 1965.

Before taping, one member of each couple drew a name of whom they were playing for, but only the TV station of where that person watches the show was revealed until the end.

Afterward, he/she made a bet (from $10–$100) on whether their partner would answer the question right or wrong (a lever was pulled which either lit up the phrase "CAN" or "CAN'T").

After this, the other couple (again, starting with the wife) went through the same process; the men then took their turns at hearing the question, and so on.

A color episode from September 6, featuring Denise Darcel and Robert Culp, was discovered in February 2009.
