This episode seems to have been removed from the rerun cycle. Adult Swim has skipped over it three times in the series rotation. It finally aired again on Sept. 16, 2009, and again on Dec. 9, 2009, So it seems to have permanently returned to rotation. The reason why it was initially removed was because the DMCA had removed it because the Archie skit contained copyright infringement. That is why they edited the episode on the Season 2 DVD release.
