One of the few extant episodes of Joey Bishop's late night talk show from the late 60s has Davis and Lawford on to plug this film. They are both looking away from Joey at the monitor as Joey sets up a clip from the film and he then says, "Let's see the clip from their new film, Salt and *Peter*."
The camera caught both Davis and Lawford whipping their heads around to look back at Joey and there was a silence of a half beat as the clip started playing and then no one could hear anything of the clip since the audience and Joey and everyone else was laughing hysterically over Joey's faux paus.
