The line comes from Adventures of Sonic the Hedgehog, the 1993 animated series where Dr Robotnik was voiced by Long John Baldry. In the episode, Robotnik says snooping as usual I see to Sonic, but YouTube Poop editors in the mid 2000s looped and stressed the middle of pingas, turning one word into a running gag. The clip spread through early meme videos and soundboards, spawning remixes and catchphrase edits, and it remains a shorthand for Robotnik and for old school internet humour.
