Mark Proksch

Mark Edward Proksch (/ˈprʊkʃ/;[1][2] born July 19, 1978) is an American[3] comedian and character actor. He is best known for acting in the television series The Office, Better Call Saul, Dream Corp LLC, and What We Do in the Shadows and as a fictionalized version of himself in the On Cinema universe.

He rose to prominence when he portrayed the character “K-Strass,” a parody of a yo-yo master, who appeared on local news shows.

Proksch had the alias of Kenny “K-Strass” Strasser early in his career, during which he appeared on small-market local newscasts as a hapless “yo-yo master.”[5] In these appearances, he fabricated stories about visiting schools to speak to children about environmentalism. When asked to perform tricks live on the air, he would display a complete inability to do any of them. The character of K-Strass was described by online magazine Paste as “the funniest thing that’s ever happened” and speaking “in a nasal Midwestern accent, with a halting cadence that was both awkward and deliberate.”[6] K-Strass was created when Proksch’s temp job at an ad agency fell through.
