War of the Pranks: The episode ends in a cliffhanger that reads The End? This is infamously used in plenty other movies and TV shows.
Barnyard Games: Peck's "problem" is revealed in this episode. While participating in the games, a number of things happen to him. He gets struck by a meteor a number of times, gets launched like a dart onto a board, and throws a projectile just for it to hit a tree and have it bounce into his face.
Pig: I'm number four! I'm number four!
Otis: (calling to Peck and Freddy) Guys, where are you? Pig is going to your breakfast!
Pig: Um, yeah see.
Otis: Pig ate your breakfast!
Freddy: What? That's sick. I'm deeply offended! (coughs up a feather)
Pip: Oh, my gosh!
Abby: Freddy, how could you?
Otis: I object.
Freddy: Me too (eggs are thrown at him).
Actor: Now listen up, whenever you hear a bell, destroy farmer.
We learn that Pig has his own answer mail questions activity.

The crop circle that Otis makes looks like the crop circle that aliens made from the movie Signs.
