Happy Birthday, Dan O'Brien! You're the only guy we know who can blow out birthday candles and hurdle over them at the same time. From your legendary Olympic gold medal in 1996 to dominating multiple World Championships, you've set a standard that even gravity struggles to keep up with.Here's wishing you another year filled with victories—though honestly, after conquering ten events in one competition (seriously?), we're not sure what's left for you to achieve. May this next lap around the sun be as impressive as your decathlon career—and hopefully involve fewer hurdles than you're used to jumping!
