I was watching an old tape last night with "Arthur's First Sleepover / Arthur's New Year's Eve", and I've come to realize that's another episode that seems to always be reserved for a specific time of the year (namely, New Year's Eve).
In fact, going over it, there's a surprisingly decent amount of episodes that are never shown in reruns at random anymore, but rather, always reserved for a specific time of year, such as:
- "I'm a Poet / The Scare-Your-Pants-Off Club" (around Halloween)
- "Arthur's First Sleepover / Arthur's New Year's Eve" (New Year's Eve)
- "D.W. Goes to Washington / Arthur's Mystery Envelope" (political holidays)
- "What Scared Sue Ellen / Clarissa is
****" (around Halloween)
- "Buster's Breathless / The Fright Stuff" (usually the day of Halloween)
- "April 9th" (Guess)
