First appearance of Jane Sibbett as Carol, Ross's ex-wife. She was played by Anita Barone in The One with the Sonogram at the End (1994), but Barone was looking for a role as a series regular and was cast as Karen Foxworthy in The Jeff Foxworthy Show (1995).
The owner of Central Perk is Terry (no surname). He is seen once more in The One with the Baby on the Bus (1995) and he is mentioned once more in a later episode where Gunther tells Rachel that Terry wants her to do the waitress training again.
This is the first time that Carol's occupation as a teacher is mentioned, albeit indirectly.
The song that Ross sings to the baby is the theme song for The Monkees (1966-1968).
Unofficially, known as "The one with the Thanksgiving Lockout".
