Doraemon began as a Japanese manga created by Fujiko F. Fujio in 1969 and grew into a long running anime about a robot cat from the future who helps schoolboy Nobita. Short voice clips from the series circulate widely on soundboards and in fan edits, where this extended hehehahaha laugh is shared separate from any single scene. Its appeal online comes from instant recognition for anime fans and its usefulness as a stand alone reaction, even for viewers who only know the character by sight.
