I absolutely love this story. According to Boston.com, John Krasinski is originally from Newton MA. He was telling Jimmy Fallon, who also happens to be a New Englander, that when he first moved to NYC he was rocking a Nomar Garciaparra jersey. All of a sudden he felt something pelt him in the back of the head. It turns out it was a cab driver who didn't approve of John's choice of sports teams.

Watch him tell the story in full below:

Oh and HAPPY OPENING DAY! I hope no one whips a bagel at your head for rooting for the Sox today.
