Why Team USA Olympic gymnast Stephen Nedoroscik tugs on his ear when he’s competing

"So, this right here [tugging on ears] is for my dad's father — my dziadek, that means grandfather in Polish — he passed away last year, unfortunately...""His name is Stephen John Nedoroscik, just like me. I'm named after him. And back when I was at Penn State, that was the thing that I did whenever I was on TV to say, 'Hey, Dziadek.' So, I've kept the tradition up, and now it also means 'Hey' to everyone that I love."
