After becoming too assertive and mean with her friends, Fluttershy looks into a puddle and sees how much her personality has changed for the worse. She immediately sobers up and begins to walk home, as a version of "The Lonely Man" plays.
Pinkie Pie reverses her side in an argument about how much to pay for tomatoes, which echoes Bugs Bunny reversing his position on "Duck/Rabbit Season" to fool Daffy Duck. She later pulls the same trick on Iron Will.
When Iron Will appears at the beginning of his assertiveness workshop, the background music is Eye of the Tiger by Survivor and later Iron Will ses a variation of the phrase "I pity the fool".
