Jared Logan is a writer for the “Late Late Show With James Corden” and host of the podcast “The Secret Masters.” He was also a delegate for Comedy Central’s “Indecision 2012” and had a half-hour standup special on that network in 2013. Whatever. What’s important to know about the “comedian of semi-national renown” (his words) is that when he was a child in rural West Virginia his classmates used to tease him with the nickname “Big-head.” It was not a reference to his intellectual capacity. Logan has a two-night, four-show run this Friday and Saturday, July 1 and 2, at the Vermont Comedy Club in Burlington. He asks that you kindly not heckle him by making fun of his large head.
