The line comes from the 1994 comedy Dumb and Dumber, spoken by Jim Carrey as Lloyd Christmas after Mary Swanson tells him his chances with her are one in a million. Instead of giving up, Lloyd treats that tiny figure as good news, and the scene became one of the film's most quoted moments. It spread through reaction videos, sports edits and meme compilations, where the same blind optimism fits any long shot, from lottery tickets to last-minute comebacks, keeping the joke instantly recognisable decades later.
