Production order

This is a list of episodes in order of production code (aka the order in which episodes were produced). 
Notes:
* Any episode that was a holdover for the next broadcast season will be styled like this for clarity.
* Season 3 and Season 7 (or broadcast Season 8) are the only seasons to fully air all their episodes in the broadcast season.
* In Season 6, seasons would start being ahead by one season due to broadcast Season 7 being the 6ACX episode holdovers that were delayed due to the 2007 Writer's Strike. As such, starting from Season 6, 
* Starting in Season 10, the episodes would get a new production code. For Seasons 1-9, their production code was styled as #(number of season)ACX#(episode number). Season 10 onwards would have their production code styled as (letter in the alphabet)ACX#(episode number). In this code style, letters like G, I and O are skipped over.
