Lilo & Stitch: The Series (2003)

S2E15 Heckler

Experiment 322, known as HECKLER, is unleashed just as Pleakley takes the stage for his first stand-up routine at Nani's charity event. Initially, Lilo finds his spontaneous quips, particularly those aimed at Mertle, entertaining. However, she quickly realizes that harsh comments can sting deeply, especially if one allows them to affect their feelings.
