Trivia: My Little Pony: Friendship Is Magic S2 E18 "A Friend in Deed"
- Hey, It's That Voice!: Cranky Doodle is Rhinox!
- I Knew It: Fans guessed that Pinkie Pie's "Smile Song" would be in this episode, and they were right! Granted, a bunch had also guessed the song would appear in "Baby Cakes", which was of course Jossed. This episode was just the next Pinkie episode on the list.
- The Other Darrin: Rose suddenly sounds much older than in her previous speaking roles. It seems that even if a background pony has a consistent name, they still won't necessarily have a consistent voice.
- When Pinkie Pie says that her birthday isn't for another 75 days, that's only 4 days off from her birthday on a real-world calendar, as "Party of One" aired April 29th, and her birthday in-universe would be May 3rd.
- To celebrate this The Hub aired a special commercial on May 3rd specifically for Pinkie's birthday. They tweeted birthday wishes too on May 3, 2013.
- Additionally, if we take this episode's premiere date as the day on which everything but the Cold Open takes place, Matilda's birthday would be June 29th.
