Loads and loads from Digimon Adventure 02. I can only give a few examples, though, because there are simply TOO MANY!
Tentomon: "Welcome to my treehouse! Actually, it's not much of a treehouse anymore, since SkullGreymon disintegrated it. Now it's more of a twig house. That's okay. I was planning on redecorating anyway."
Davis: "We don't care about your stupid tree, Tentomon!"
[Later]
Veemon: "Now that Tentomon is out of his tree, maybe we can climb it and have a look around."
Davis: "You bet!"
Tentomon: "And stay out of my tree!"
[Later]
Tentomon: "And don't touch my tree! I know exactly how many pieces of bark are on it."
[Later]
Tentomon: "And tell them to stay out of my tree!"
Izzy: "Uh... you bet."
Woodmon: "I am Woodmon! I cannot be defeated!"
Flamedramon: "Flame Shield!"
Woodmon: "Hey! I'm being defeated!"
Tai: "I’m sorry we attacked you Agumon"
Agumon: "I’m sorry too!"
Tai: "I'm sorry that you’re sorry!"
Agumon: "I’m sorry that you’re sorry that I’m sorry!"
Tai: "Tell you what, I won’t be sorry anymore, and you don’t be sorry either, okay?"
Agumon: "Sorry."
Ken: "You will bow down before me!"
T.K.: "Sorry, the floor's kinda dirty."
"I haven't been here in a while. It's... the same. Including the smell of your socks."
—T.K. visits his father and brother's apartment.
Izzy: "Come on, Davis. Give it a try."
Davis: "Wha—! Who, me?"
Kari: "No, silly, he means the other boy with goggles." *Sarcasm*
Davis: "Oh, where is he?"
“What do you want to do, walk up there and say, ‘excuse me, do you mind if we take a couple of minutes and tear down this building?’”
— T.K. thinks that Davis' plan is a little easier said than done.
Digimon Emperor: "Hey, Digi-fools. Do you honestly think that your new Digimon can beat me? He couldn't even be my flashlight!"
Davis: "Oh yeah?! Well sticks and stones may break my bones, but when Magnamon gets a hold of you, he'll kick your-!"
Digimon Emperor: "But! You didn't let me finish. He would make a good nightlight."
"Today's entry will be Tuna Surprise. Unfortunately, we didn't have any tuna. That's the surprise!"
^ I personally found these hilarious!
