LOS ANGELES (Zap2it.com) - When the fourth season of "Insomniac" premieres on Comedy Central next week, it will likely be the last for the late-night travelogue/bacchanal.Host Dave Attell says he still enjoys doing the show, in which he explores nightlife in cities where he performs his stand-up routine, and can see doing an occasional special. But as the show has become more popular, it\'s also become harder to make."It\'s a victim of success," Attell tells the Boston Globe. "We\'d go to a bar, and in the beginning nobody would know who we were, and then everybody knew and it became a circus." To avoid that, three of the season\'s shows were shot in Europe, as Attell traveled to London, Dublin and Amsterdam. He was there during the build-up to the U.S.-led war in Iraq, which made for some interesting interactions on camera."People would be at a disco, and some guy would be like, \'Tell Bush what he\'s doing ...,\' " he says. "I\'m like, \'I don\'t know Bush. We\'re supposed to be drinking.\' " The new season of "Insomniac" premieres at 10 p.m. ET Thursday, May 29.
