in mr monk and the leper when randy goes to his ex-doctors/dermatologists office and trys to take his picture off the wall, he accidentally knocks off a small picture with a silver frame which smashes on the floor, when they cut back to the scene the picture is intact and then back on the wall, then randy rips his picture frame off the wall which shows him with acne and the plaster comes off with it, then when it cuts back the wall has been repaired and replastered.
