I'm remembering, perhaps mis-remembering, a movie that may have been titled, "How To Cheat On Your Wife." The scene I recall had Sid Caesar, caught flagrantly in bed with another woman, calmly confusing his wife, (Imogene Coca).
He and the woman get up, get dressed, make the bed, and so forth, all the while denying that anything happened, or is happening.
The scene ends with the wife, looking around at a room which has no evidence of what she knows she saw, saying, "Uh, how do you want your breakfast?"
It works I tell you!
