Rolf was created for Ed, Edd n Eddy, the Cartoon Network series that ran from 1999 to 2009 about three friends in a suburban cul-de-sac. Voiced by Peter Kelamis, Rolf stood out as the son of a shepherd from an unnamed old country, with customs and sayings no one else understood. Clips of his lines circulated on soundboards and in YouTube edits during the nostalgia wave for 2000s cartoons, where his dead serious delivery still works as a shorthand for bizarre overconfidence.
