What are your favorite examples of "tomato cans" pulling off upsets against a top contender?

My favorite examples are Mike Dixon knocking out Alex Garcia in two rounds after he went on a losing streak losing to Ray Mercer, Bruce Seldon, Lennox Lewis. Or when Jesse Ferguson upset Ray Mercer in a ten round decision. What are your favorite examples of a "tomato can" fighter scoring the unthinkable win against a top contender or even against a champion?
