Nani is having trouble organizing a charity dinner, so Pleakley offers to help entertain by providing stand-up comedy. However, when an experiment designed to mock people appears and leads Lilo down the wrong path, she and Stitch have to stop him before his heckling ruins the event.
- Moral: Words can hurt.
- Jumba was secretly annoyed by Heckler, hinting that he doesn't always appreciate some of his experiments, though it is shown in other episodes as well.
- Heckler makes fun of Lilo's nose, which is ironic, considering that many humans actually have big noses.
- When Heckler starts insulting Hämsterviel, the first two scenes of his lip movement have no dialogue.
- Despite Pleakley's failure at being a stand-up comedian, he still manages to entertain the audience by throwing in some impromptu humor.
