In the episode "54-40 and Fight", where the kids are arguing over who gets the trading stamps and they decide to put all the stamps together and get one big thing, Cindy adds the number of books they have incorrectly. Also, while they are building the card house Jan's hair changes from up in a ponytail to straight down her back almost every time the camera switches angles. After Tiger knocked the card house down a few cards remain standing even though Mike pushes them down several times.
