The Trailers for the film in which Stitch disrupts Award Bait Song scenes from other disney Movies. My personal favorite is the Beauty and The Beast one, in which Stitch crashes the chandelier, Beast and Belle roll out of the way, Belle huffs "I'll be in my room." and stomps off, Stitch giving off a Wolf Whistle as she passes by, saying "get your own movie!"
Lilo:(on the phone with Bubbles) Oh good, my dog found the chainsaw! (hangs up, leaving Bubbles terrified at the other end of the line)
After Lilo tells Stitch to build something and he sets out creating something we can't see, at first.
Lilo: (completely deadpan) Wow. San Francisco.
Afterwards attacks it, leading Lilo to say:
"No more caffeine for you."
Stitch learning to dance.
When Cobra confronts Nani about losing her job, Stitch walks up behind Nani while holding a book. He stares innocently at Cobra for a moment, growls and, without any provocation at all, chucks the freaking book at Cobra's face.
When one of the lenses of Cobra's sunglasses pops out as a belated reaction to the hit.
The look on David's face when Lilo asks him to give everyone a lift to the shore. Namely, Lilo, Stitch, Nani, Pleakley, Jumba, and Gantu (although the last one is probably big enough to just wade).
"Uhh...sure. But I'll have to make two trips."
"BLUE PUNCH BUGGY!" Stitch whacks Jumba with a blue punch bug car (the owner: Nani) "NO PUNCH BACKS"
This is made even funnier when the TV show reveals that Jumba did.
Pleakley discovering the dietary habits of Earth's most "endangered" species which is later revealed to be a ruse by Cobra Bubbles.
Pleakley:[Gasps] Don't move! A mosquito has chosen me as her perch! She's so...beautiful...look! Another one! And another one...why, it's a whole flock! And they like me! They're nuzzling my flesh with their noses! And now they're, uh...they're...[Camera cuts away to an aerial view]WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!
This exchange, when Nani first sees Pleakley and Jumba in disguise:
Nani:(to Pleakley) Your head looks swollen.
Jumba: Actually, she's just ugly.
After Stitch steals a tricycle, Jumba talks about how his programming will draw him to large cities, where he'll causes chaos. Stitch cycles around the island trying to find an city, only for Lilo to tell him that there isn't one and he has a fit.
