In the Tim Conway/Don Knotts movie, there is a slipup when they are meeting the staff of the Morley Manor. When they first begin walking down the line, the Upstairs Maid (Hilda) has Tim Conway's business card between her breasts. He has not given her the card yet! When they walk back down the line and meet each individual, he gives her his card and it is then that she places the card.

This movie can be ordered on DVD from 800.com. The movie has been out of circulation for some time now, and has only recently been re-released by Hen's Tooth Video. Great comedy adventures.
