I once stumbled across a video on the Two Minute Papers YouTube channel: https://www.youtube.com/@TwoMinutePapers

I remarked to myself how much the speaker sounded like Ren Hoëk, from The Ren and Stimpy Show. Then I looked up the name of the channel host: Károly Zsolnai-Fehér.

I thought to myself: Huh. Hungarian. That explains the mathematical prowess—and the voice. (Ren's voice is a pastiche of Hungarian actor Peter Lorre.)
