Jason Sudeikis guest stars in this episode. Later Charlie Day and Jason Sudeikis costarred in Horrible Bosses.
The baseball card in the time capsule is of Phillies' outfielder Gregg Jefferies. He played only 3 1/2 seasons with Philadelphia (1995-98), by which time his best years were behind him.
Mac mutters "future All-Star" when looking at the card, but Jefferies' only 2 All-Star selections were before he played for Philly, and his status as a Hall of Famer (likely what Mac meant, as Jefferies retired in 2000) was never a possibility, making the card a fitting addition to the collection of ironically awful and useless junk (i.e. Korn CD, laser disc, etc.) the gang put in the capsule.
Dave Foley (Principal MacIntyre) and Rene Auberjonois (Dr. Meyers) both appeared in the 2010 video game Fallout: New Vegas.
This episode features Schmitty (played by Jason Sudekis). Sudekis provided the voice of Zorn in the TV series Son of Zorn (2016). Johnny Pemberton, who plays a student in Dee's class in this episode, plays the son of Zorn along with Sudekis.
