Continuity mistake: Bartman Begins: When Bart is reading the manual, there is a 360 degree panning shot of him reading. When the shot is on the road behind him, there is a museum in the background and a sign saying "Springfield Museum of Natural History." A few seconds later, when Homer arrives, the sign in front of the museum is still there, but the name has vanished from the sign. When Homer and Bart climb into the sewer, the name has suddenly reappeared on the sign.
