This isn't my story but it did happen to my close friend I run with so close enough.
My friend and her son were on an expedition looking at colleges on the east coast. They were visiting Georgetown and my friend had somehow set it up that her son, a tennis player, was going to hit some balls with the team's assistant coach, or pro or whatever. So they show up at the court a bit early and the coach is standing around talking to someone. He beckons them over and introduces them to "Malia"...Malia Obama, that is.
Also one of the secret service guys had on one of those Gilligan-looking hats.
