This gem from "Martha in Charge", when Helen got Laryngitis:
Helen's Mom: I hope Helen recuperates.
Martha: She shouldn't do that! She should get better!
Helen's Mom: That's what recuperates means.
Martha: Really? But that sounds like a bad thing! Like "Don't come in, I just recuperated all over the floor..."
Heck, the entire episode was hilarious, Home Alone-style.
In "Carolina's Gifted," Carolina has a gift certificate that she says she's "squirreled away" for nearly a year. Martha spends most of the rest of the story desperately trying to find out where the squirrel is. Also, later on she's asked what she would "splurge on," if she could. She gets very upset, saying that she doesn't splurge on anything: she's housebroken. She becomes disappointed to learn there's no real squirrel.
Similarly in "Martha Camps Out", Martha keeps asking "Who's Big Minnie!?".
In "Martha Gives Advice", Carolina fainted, not because she discovers Martha can talk, but because she's been listening to her advice, which includes dressing up like Helen.
Also, the part where Martha starts giving advice that should only apply to dogs...and it also works for humans!
Carolina "defending" Helen over how she dressed.
In "Wagstaff Races", TD and Alice's kart gets sent off by the wind and off to sea.
"STOP SPYING ON ME!!"
In "Martha in the Doghouse", TD used his belt to hold something up, but it collapsed and his pants fell.
In "The Missing Metal Mystery", TD believes HE stole his own trophy and the metals from the junkyard. He spends the entire episode trying to prove he's guilty.
In "Truman On the Ball", TD picks up a book at the library, and spends the rest of the episode commenting on how "I don't think I should have read this book at my age" and making jokes about the plot. The book? Moby-Dick.
In "Dogs in Space", TD wears a jetpack but it flies off into the sky, as he forgot to buckle up. Helen tried to tell him that.
In "Alice Covers Up", TD gives Alice lemons to wipe off the orange dye. They don't work, but TD said she smells zesty. Alice throws a lemon at his head.
TD has an idea of getting dog-vision sunglasses for everyone at the pool party to wear so Alice wouldn't be embarrassed.
Helen: Do those sort of glasses even exist? TD: No. But it be nice if they did. [Alice slams her head on the table.]
Helen gets tired of Martha and Skits bickering over the flying squirrel toy in "Dog Fight" so she makes them watch a video about sharing that parodies Sesame Street. The dogs seem to get the moral when Helen asks them. Later, TD and Alice were still arguing about Martha and Skits' fight so they ended up getting the same treatment. Unlike the dogs, their response started with this:
Helen: What did you guys learn? Alice: I learned that boy puppets are more selfish than girl puppets.
In "Perfectly Martha", Martha was watching a demonstration of a "perfect dog":
Otis: You see, now he's perfect. Martha: That's not perfect, that's terrible! Otis: Who said that?! Dr. Paplum: Otis, calm down. Otis: I will NOT calm down! (the crowd is perplexed at his sudden outburst) Otis: I mean, how can I calm down when I am so excited to train. And by train, I mean, teach your imperfect dogs to be perfect. Martha: What is he talking about? Dogs are already perfect. Otis: Alright! Who said that? (confronts a random woman) Was it you? Lady: I think it was the dog. (points at Martha, who just stands there) Otis: "I think it was the dog." (threateningly) I'm onto you, lady.
Otis: That's the same dog from this morning. Did that woman put you up to this?
In "Martha Sings", Helen's dad is obsessed with Martha's singing.
In the first episode, Martha kept talking and talking, until she starts saying "blah blah blah...".
Helen: It's great that she's speaking. But there's speaking, and there's speaking, and speaking. TD: Helen. Helen: It's great that she can communicate. But does she have to communicate so much? It's like she wants to discuss and discuss and discuss. TD: Helen! Helen: And it's not even a discussion. Cause when you discuss, the other person gets to express her opinion too, you know what I'm saying? TD: I think you— Helen: It's like she's giving a lecture. Doesn't she know how annoying it is? (we pan out to see their teacher Mrs. Clusky standing besides Helen) Just hear someone jabbering on and on and— (Helen sees Mrs. Clusky with her hands on her hips glaring at her) Oops. TD:Class started five minutes ago. (Helen lowers herself in her seat in embarrassment.)
In "Martha's No Dummy", Helen's dad laughs loudly at T.D. and Martha's knock-knock jokes. Helen's mom is embarrassed.
In "Martha's Dirty Habit", all the dogs in the neighborhood chase after Martha for getting them in trouble for digging up their owners' front lawns.
In "Skits Behaves", T.D. tries to show who's boss by making eye-contact with Skits. After 10 seconds of glaring at each other, T.D. gives Skits his other half of the sandwich.
TD: I wasn't hungry anyway.
In "Camp Truman", Truman tries to get Milo to see how awful camping would be, so Milo wouldn't find out the camp he wanted to go to has been closed.
Truman forcing Milo, Truman and Helen to wash dishes, but Truman and Milo were having fun with the soap bubbles.
Truman: Alright, kitchen patrol is over! TD: Aww, but my fingers were just starting to get wrinkly.
TD: I got this great new comic book. Truman:(blows whistle) No talking about comic books! Milo: This is really nice. Just hanging out and relaxing. (Truman blows whistle again) Helen: Alright Truman, this is gone far enough! Truman:(*whistle*) No standing up and saying "This is gone far enough!" (Helen groans)
After finding out Camp Winneka is opening at a new place (Truman made the page talking about that into a pirate hat):
(Helen, Martha, and TD glare at Truman) Truman: Well, we can all learn something today.
In "Never Forget to Remember", after Skits remembered where the ball was:
T.D.: If only we were as smart as Skits. Martha: That sounds so wrong.
