The Four Guards were featured in the movie Labyrinth. They stood guard in front of two doors. One of the doors would lead to the castle at the center of the Labyrinth, while the other door would lead to "Babababum certain death". The bottom two guards were clueless as to which door leads where. The top two guards were the only ones who knew the answer. In the real world, the challenge represented by the guards is called a Knights and Knaves problem. The novelization refers to these characters as Alph and Ralph and Jim and Tim, and the fabrication credits group the guards under Alph and Ralph.
