Continuity Nod: The Professor recalls the girls saving the world from being turned into dogs, defeating outer-space invaders, and matching wits with "Him."

The girls point out Professor Utonium does all that, since they never had a mom as they weren't naturally born.
Testosterone Poisoning: "Fools! I feed off your expulsions of manliness! The more manhood you bring against me, the harder I become!"
Underwear of Power: After being rejected from the group, Buttercup mocks Major Glory for wearing his underwear on the outside of his costume.
