Daily Show writer JR Havlan has been a writer on the show since the very beginning. Not just the beginning of the Jon Stewart era, but a writer since the very first episode of the show, when it was hosted by Craig Kilborn. And after over 18 years on the job, yesterday was his last day. Because he’s been a part of the show since its inception, Jon dedicated the Moment of Zen to him last night, showing a clip from the earliest days of the show that featured Havlan. It’s not clear what he’s doing next – he’s also the host of The Writers Bloc podcast – but it seems like he’s really earned a break before figuring it out.
