The television version was extended slightly in at least two places: In the school bathroom when Rick was explaining to Gary and David what the problem all of them were experiencing was, he says that the crabs were "a little present from Ruby." When they went to the drugstore to seek a remedy after the attempt to "drown" them failed, they first talked to a female assistant before talking to the familiar male druggist. The "Assistant Druggist" character appears in the end credits, but not in the version on VHS or DVD.
