Hans Niemann

Hans Niemann was an up-and-coming chess player who wanted to become a folk hero by breaking fair-play rules. However, it failed, as everybody still thought he did butt stuff.

I could go on, but there's really no need to. The dumbheadedness speaks for itself.

If there's one thing you can't say Hans Niemann does, it's "get high off his own supply," so to speak.
