The Sly clip comes from a user-generated soundboard upload tagged PA - Sly, and no original film, show or recording is documented for it. Short name drops like this spread because they are easy to reuse: a three-second vocal tag fits anywhere an editor needs a fast beat of attitude. On soundboard sites it sits alongside other quick stings, picked up by creators who want a snappy identifier rather than a long sample. Its staying power comes from brevity, since a clip this short never feels dated.
