The topic is a person whose clothes style, hairstyle, facial hair, etc. seems to be based off an actor or comedian, where the latter’s is intended to be somewhat humorous, but the former seems unaware or oblivious to the comedic aspect of their appearance. The homage does not need to be intentional, but it must be chronologically after the comedic original. And it should be an intentional choice by the person, not just an accidental facial resemblance.
Examples:
Adolph Hitler’s toothbrush moustache which was previously sported by comedians like Oliver Hardy and Charlie Chaplin.
Or Kim Jung Un’s hairstyle, which seems reminiscent of Vir Cotto’s Centauri crest on Babylon 5.
