The Recess Gang breaks-up when a report to write about their best friend prompts division as all five of the others write about T.J., prompting T.J. to realize that he has five best friends, not just one best friend.
- Coloring error: There's one point in the episode where everything in the scene colored red becomes black. This was due to the ink & paint department running out of red ink and had to use another color.
- Animation/lip-synching error: When Sam is talking to Gus, it's animated as Dave talking.
- Continuity error: As soon as the gang enter the playground, Randall asks T.J. to be his friend for the assignment. However, Randall isn't in class with the gang, so he wouldn't have gotten it. There could've been a possibility that Randall's class assigned it as well.
