There was a quick EUF scene in the movie "The Incredible Burt Wonderstone". In it, the titular character insults his assistant and she quits. Needing a new assistant, he asks one of the stagehands and pretty much names her the new assistant on the spot. While she knows all of his tricks and is a big fan of his, she is hesitant due to stage fright. While trying to explain herself, the costume person is already changing her wardrobe, which includes taking her shirt off out of nowhere, exposing her bra. The new assistant instinctively covers herself upon her shirt ripping open and then off of her. You can watch it here. It's the 1st clip of this montage
