The line comes from the Brazilian Portuguese dub of Warner Bros.' Looney Tunes, where Bugs Bunny's original English catchphrase What's up, doc is rendered as que que ha velinho. Bugs has used the greeting since his early cartoons in the 1940s, usually while chewing a carrot and staying calm under pressure. In Brazil the dubbed version became just as quotable, circulating in reruns, edits and soundboards. It sits alongside other dubbed cartoon staples like the Woody Woodpecker Laugh that Brazilian audiences grew up hearing on television.
