i was confused while reading an online episode guide because nick at nite didn't air the episodes that i thought were originally after the 2 part season opener for season 4.

instead they're airing 2 episodes from the 5th season that were suppose to air originally for the 4th season. as i came to find out.

here is the guide i am reading.

the guide i was originally using was at epguides.com
