Bob & Carol & Ted & Alice (1969)

Continuity mistake: In the restaurant kitchen scene, Carol Sanders takes hold of the waiter's left hand. In the next shot, she is holding his right hand.

Trivia: Right at the very end, when the group of people is milling around staring at each other, watch for Barbara Feldon, from Get Smart.
