Funny or Douchey?

Dan Heimiller won the $1,000 Seniors Event at the World Series of Poker for $627,000. Nothing douchey about that.
He did it while wearing a T-shirt that says "Winner! Winner! Chicken Dinner!"

Even that, I wouldn't say is douchey.
A long time ago Papa Poop told me about a guy he played blackjack with in Atlantic City. Every time the guy got an ace he said "king of hearts." After 20 times, he finally got the king of hearts and said he called it.
That's what Heimiller does with the shirt. He wears it every single time in the hopes of finally winning?
Is that douchey?
