There is no widely documented original source for Pitidos 2 Furbo, and the name appears to come from a user-uploaded soundboard entry rather than a film, game or television show. Short beep sounds like this circulate widely because they are easy to recognise, easy to reuse and short enough to fit into fast-paced edits. The '2' in the title suggests it is part of a small series of similar beep clips, although the other entries are not well documented. Its continued use comes from that simplicity: a brief electronic signal that works in almost any comic or reaction context.
