The line comes from Bean's Show, an object show built around everyday objects as characters, and is spoken by Balloon in episode six during a brief, self-deprecating exchange about his health. In the scene he cheerfully claims to have several diseases, including rabies, before admitting he is thirsty, a contrast that object show fans picked up on and turned into a shareable clip. It remains in circulation because the delivery is short, quotable, and easy to drop into edits, reaction videos, and fan-made object show content.
