Real-Life Relative: Will Arnett has a cameo as a creepy guy Leslie dates in one episode. He is married to Amy Poehler (Leslie) in real life. Also, Nick Offerman (Ron) and Megan Mullally (Tammy 2) are married in real life.
What Could Have Been: Deleted scenes and DVD audio commentary reveal that several Pawnee townspeople would become more heavily recurring characters in future episodes. These characters included conspiracy-theorist Barry, anti-parks advocate Kate Spivack, and Andy's neighbor Lawrence. When the Pit 48 plotlines were demphasized in the next season, the need for these characters diminished. However, Lawrence made several cameo appearances in later episodes. Barry appears very briefly in season two in the episode "Sister City", though he only has lines in a Deleted Scene.
