Bait And Switch / Kaeloo

• In the pilot, Stumpy needs to touch a wall before Quack Quack can get there, when he sees a pair of roller skates lying next to a chainsaw and gets an idea. Instead of using the roller skates to skate to the wall, he activates the chainsaw and puts it on the ground so it drags him along.
• In one episode, Olaf captures Kaeloo and Mr. Cat, and tells them to "prepare to suffer"... before turning on some music and singing.
• In the episode "Let's Play Market Vendors", Mr. Cat and Stumpy rob a supermarket, and Mr. Cat threatens to shoot anyone who moves. Kaeloo starts waving her arms and yelling for help. Gunshots are heard. It's then revealed that Mr. Cat shot Quack Quack, not Kaeloo.
• In "Let's Play Gangster Poker", Mr. Cat says he has a surprise for Quack Quack, and leaves some yogurt on the table in front of him. Quack Quack reaches out for the yogurt, and then Mr. Cat whacks him on the head with a baseball bat and yells "Surprise!"
• In Episode 85, Stumpy and Quack Quack, both having a Potty Emergency, reach the bathroom at the same time. Stumpy says that there is "one final solution" and they both raise their fists... to play Rock–Paper–Scissors.
• In Episode 113, Mr. Cat makes a slideshow about vampires to show to the rest of the characters. Kaeloo looks at the first slide and is absolutely horrified... not because it's a scary picture of a vampire, but because Mr. Cat accidentally put up a "private" photo of her that was supposed to be for his eyes only^note It's not a nude photo, but she's still quite embarrassed.
• Usually, when the characters are stuck in a dark place and can't see, they yell "Quack Quack, lights!" and Quack Quack uses his Eye Beams as a light source. In Episode 79, Kaeloo yells "Quack Quack, lights!" and Quack Quack... turns on an actual lamp.
• In Episode 180, Mr. Cat teaches Stumpy about marital disputes. Kaeloo tells Mr. Cat that he shouldn't be teaching Stumpy about marital disputes because that's not appropriate for a kid Stumpy's age^note Stumpy is ten, and Kaeloo and Mr. Cat are around twelve. Stumpy tells Kaeloo that he watches things that "aren't for kids his age" on the internet all the time. Kaeloo angrily grabs his laptop to see what he's been watching. It turns out that he was looking at knitting tutorials for old ladies.
• In one of the season 4 episodes, the main four are judging a singing contest. One of the teams consists of Polar Opposite Twins Pretty and Eugly, the former of whom is a beautiful and popular fashionista and the latter of whom is overweight and often made fun of in-universe for being ugly. Their act involves Pretty dancing and Eugly singing. A fight breaks out between the two and Eugly storms off, prompting this response from Mr. Cat:
  Mr. Cat: I have to admit, the ugly one really isn't nice... her sister, on the other hand, sings very well.
• In Episode 91, Mr. Cat makes a "who am I?" riddle about something that's soft, green, and flabby. Kaeloo takes umbrage because it sounds like he's referring to her, but it turns out that the right answer was a European oyster.
