"Say Cheese": Heathcliff turning himself into a lion to scare a kid who sneezed on him.
This dialogue in "Boom Boom Pussini":
Hector: Okay Mungo, go fish. [Mungo leaves and returns with a fishing hat and a fishing rod] Hector: No! We're playing the game "Go Fish"! Mungo:(blushes) Oops, sorry. [Heathcliff shows up and whispers to Hector's ear. Hector snickers and puts his card down] Mungo: Gin! I win! Hector: GRRRRRR!! What are you, a wise guy! Heathcliff?! [Heathcliff chases after Hector.] Wordsworth: What a shame, that's the end of the game. Mungo: We can always go fish. [Wordsworth smacks the fishing rod off Mungo's hand.]
"House of the Future": After seeing Riff-Raff and Cleo sneak into a carnival by hiding underneath a woman's dress, Hector, Wordsworth and Mungo try to do the same to a different woman. Needless to say, it doesn't end well for them.
In "Big Foot", Riff-Raff, Hector and Wordsworth use Mungo as bait by dressing him up as a fish.
Mungo: My mommy never dressed me like a tuna!
In the credits, Hector takes Cleo's hand and leans forward to kiss it. Wordsworth crashes into him on his roller skates and Cleo stands there with an expression that all but reads "Oh my!".
