Joe Cartoon was one of the defining sites of the early Flash animation era, built around short interactive cartoons by Joseph Shields, including Frog in a Blender and Hamster in a Microwave. Clips and catchphrases from that period kept circulating long after Flash faded, shared as pure internet nostalgia. Dur Duh Do Duh survives in that same spirit, filed alongside other goofy ahh sounds and reaction clips that creators reuse whenever a scene needs an instantly recognisable dose of old school, deliberately stupid cartoon energy.
