some dude with a foot for a head and a doctor's metal circle thingamabob on his head, an ancient ytmnd meme (which were called "fads" on ytmnd), called "foot doctor", where the scene would be interrupted with a robot voice saying "foot doctor", and a weird version of the music from Hydrocity Zone from Sonic 3 would play. The point was to make fun of "interruption fads", but it ended up becoming an unironic fad. that's right, a meme so ancient it predates the word meme. I'm getting old
