American Football
  • Joe Namath's famed guarantee of a Super Bowl victory by the 1968 New York Jets was seen as this, as the AFL to which the Jets belonged was perceived as an inferior league to the NFL. By following through with that guarantee, the Jets created the Super Bowl (which to that point had been something more akin to an All-Star game, with the NFL Championship considered to be the true Championship game), and helped dispel the notion that the AFL was an inferior league and made the impending merger more palatable to long-time football fans.
  • The controversial post-game speech by Seattle Seahawks cornerback Richard Sherman after the team's victory over the 49ers in the 2014 NFC Championship game.
    "Iím the best corner in the game. When you try me with a sorry receiver like Crabtree, thatís the result you gonna get. Donít you ever talk about me. Donít you open your mouth about the best or Iím gonna shut it for you real quick."

  • Boston Red Sox DH David Ortiz is quite good at these, but none may be more memorable than the one he gave at the first game back at Fenway Park after the Boston Marathon bombings.
    "This is our fucking city. And nobody's gonna dictate our freedom. Stay strong."
    • That afternoon, Ortiz — in his first game appearance of 2013 — drove in the tying run that would prove crucial in the Red Sox' 4-3 win over the Kansas City Royals.

  • In a time where NBA teams hadn't won back-to-back titles in 19 years, coaching legend Pat Riley of the Los Angeles Lakers said to the fans "Next year, we're gonna win it again!" They did.
  • Despite being a top seed in the 2011 NBA Playoffs, the seven other teams in their conference openly expressed a preference on going up against the Dallas Mavericks (who would go on to win the title), believing they were an easy mark. Mavericks guard Jason Terry acknowledged the conceit and welcomed it:
    "They are going to get their chance, one by one."

  • "Marvelous" Marvin Hagler, before his match with Sugar Ray Leonard, commented on Leonard's troubles with a detached retina, saying "If he's fool enough to fight me, I'm fool enough to rip his eye out".

Ice Hockey
  • 1994 Stanley Cup playoffs, Eastern Conference Final. The New York Rangers, 54 years removed from their last Stanley Cup victory (the longest Cup drought ever), just dropped Game 5 of their best-of-seven series against the New Jersey Devils 4-1 on home ice. Rangers captain Mark Messeir then came out and publicly declared the Rangers would win Game 6 at Brendan Byrne Arena (the Devils' home arena) to send the series back to Madison Square Garden for a deciding Game 7. After two periods the Devils were up 2-1, then Messier himself scored a natural hat trick (three goals in a row) in the third period and the Rangers win Game 6. Rangers win Game 7 in double overtime, then edge the Vancouver Canucks in seven games to win the Cup and end the Curse of 1940.

Mixed Martial Arts

  • After dislocating his shoulder in a crash in Tour de France, and told it would be the most painful three weeks in his life, Aussie cyclist Adam Hansen simply wrote: "I eat pain for breakfast! Bring it on" on Twitter. Hansen holds the record for most consecutive grand tour completions, 13 as of the end of 2015 (the Tour in which he crashed was his twelfth).
