Outward Bound: Part 1 - S6-E15
Revealing mistake: When Mr Baxter walks into the boys' dormitory, he gets soaked by a bucket of water that is placed over the door. If you look carefully, you can see that Baxter has his eyes closed before the water falls on him.
Revealing mistake: In the final scene just before Stewpot and Duane spot Pogo with his girlfriend, at the start of this scene you can see a little boy jump up over the wall and wave to the camera.
