I saw one filmed once. Some guy gave me a little bitty light weight t-shirt and told me to put it on and just hang in the background. What an opportunity! So I did the old blanket switch and there I was with this little bitty top on, breasts all sticking out when one of the film managers told me to get off the set. Turned out that the guy didn't know squat about the video-just wanted to see if I'd put the dang shirt on!!
