Ever since Mysterion first appeared on South Park last year, fans have speculated about the superhero's secret identity. Theories have ranged from Kenny to Mr. Hankey to Elton John to David Duchovny to Supreme Court Justice Sonia Sotomayor to Neil deGrasse Tyson to The Judds to Bruce Wayne to your mom to Ike Brovlovski. Well, if this preview from Wednesday's all-new episode is to be believed, the speculation is about to end, and we'll finally all know for sure if the man behind Mysterion's mask is Garrison Keillor or not.
