The line riffs on Muscle Man's running gag from Regular Show, the Cartoon Network series that ran from 2010 to 2017, where he constantly asks 'Do you know who else...' before a 'my mom' punchline. This dementia version swaps the expected ending for a more absurd twist and spread as a short meme clip on social video apps. Its familiarity comes from years of fans quoting the setup in comments and remixes, keeping the format alive long after the show ended.
About this sound
Muscle Man's 'do you know who else has dementia' meme sound effect from Regular Show, used for forgetful moments and absurd punchlines in edits.
This clip captures Muscle Man from Regular Show delivering his classic setup line with a twist, asking who else has dementia in his loud, drawn out voice. The delivery builds like one of his usual 'my mom' jokes, then lands on an unexpected and darkly silly answer that catches viewers off guard. The stretched phrasing and confident tone make the moment instantly recognisable, even without seeing the scene. It works because the joke sounds serious for a second before turning absurd, giving edits a quick burst of awkward, quotable humour.
