(I am probably the only person to write a review on an episode of Roundhouse).
I love this episode, if this is the episode I am remembering. This is the one where they talk about peace and the girl (I'm sorry, I can't remember if it is a girl or a boy) wears the Mercedes logo around her (maybe his?) neck.
This is the most memorable episode of this show. I think it might be because it was the episode shown in Nickelodeon's "We Had Them First" marathon they had some years ago.
My sister and I laughed at this episode and I know people would enjoy watching them today if they were aired.
