Numberwang comes from That Mitchell and Webb Look, the British sketch show starring David Mitchell and Robert Webb, where it parodies daytime quiz shows with contestants guessing numbers and a host declaring a winner for no clear reason. The sketch became a cult favourite because its rules were intentionally impossible to follow, which made the winning call easy to quote out of context. Online, the clip spread through soundboards, reaction videos and edits, where it now works as shorthand for treating any number, score or result as a dramatic victory.
