Jon Rineman is a writer and stand up comedian. A 2005 Emerson College graduate, Jon has been a regular at Harvard Square’s Comedy Studio since 2004. Based in Boston, he became a freelance monologue writer for The Tonight Show with Jay Leno, contributing daily jokes about current events to the top-rated show in late-night television. In 2005, Jon was published in the Improper Bostonian’s annual humor edition. After honing his craft for a few years as a writer and comedian, Jon was hired to be a writer for NBC’s Late Night with Jimmy Fallon, which replaced Conan O’Brien’s Late Night show. Jon has continued to serve as a monologue writer for Jimmy Fallon. Recently, Jon also appeared as a featured stand up comedian on Late Night with Jimmy Fallon. He appears regularly at all of the top New York City comedy clubs, including Caroline’s on Broadway and Stand Up NY on the Upper West Side of Manhattan. Jon lives in New York City. At 32, he’s the head monologue writer for “The Tonight Show With Jimmy Fallon,” the apex for someone whose ambition is to make people laugh. “Everyone here is so fun and cool, and I’m just kind of this weird, lame guy,” he says. “Sometimes, I wonder how I’ve lasted.” His colleagues and fellow comics know. They say Rineman, a 2005 Emerson graduate who’s worked for Fallon for six years, is indeed dorky, but he’s also a skilled and prolific comedian.  As relentlessly earnest as he may seem, Rineman can grind out dozens of gags a day, and a good percentage of them make it into Fallon’s monologue. Still, it’s fatiguing being funny every day, and Rineman isn’t sure how long he can keep writing one-liners. Perhaps with an eye toward life after “The Tonight Show,” he’s been honing his stand-up routine, making three or four club appearances a week after wrapping up work at 30 Rock.
