Fortunately for Curry, Michelle had his back, sharing how to get inside the head of the POTUS:
Obama: You should trash talk back, Stephen.
DeGeneres: Give him some things to say.
Obama: Tell him about his ears. Here's one. Here's one. If you're putting, tell him, 'The shadow from your ears is really messing up my putt.'
DeGeneres: That is low.
Obama: That is what trash-talking is.
Curry: It's not fair, though, he's got 50 Secret Service out there, so if I trash-talk, he just gives them the look.
Curry, who's a 2-handicap on the links, told Ellen that the last few times he's played golf with Obama, the president got the best of him. He refused to divulge Obama's handicap as a golfer, however. That's top secret information.
