Cap's first big break came at the 2003 Just For Laughs Festival in Montreal, where he impressed the industry observers enough to offer him a sitcom deal. It was then he was able to officially trade in his weed whacker for a microphone full-time. John is now applying his blue-collar work ethic to the stage, where he performs nearly 365 nights a year.
John has made multiple appearances on The Tonight Show with Jay Leno, Comedy Central Presents and performed as part of Blue Collar Comedy: The Next Generation in 2007 with Bill Engvall. The problem now is that Cap is often compared to Larry the Cable Guy. He shares, "I love all my blue-collar comedy fans because I can relate to them, and that's pretty cool. But the next jackass who yells 'Git 'er dun' at me is gonna git 'er throat punched!"
In 2008, John's first feature film, Vince Vaughn's Wild West Comedy Show (also starring Jon Favreau and Justin Long), was released by New Line. The comedy documentary followed Vaughn and 4 stand-up comics as they toured the country. Moving forward, John went on to host the 2008 CMT series Mobile Home Disaster. During that time, his one-hour special Meet Cap premiered to great numbers on Comedy Central. Warner Bros. released the Meet Cap CD/DVD in 2009 and it is currently available to download through Netflix, iTunes, and Amazon.com.
In addition to touring nationwide, John can be seen alongside his pal Chelsea Handler as a regular on her E! hit show Chelsea Lately. John shares, "It's like hanging out at my buddy's house and getting a check for it! It really is the most fun I've had since I got into comedy. I've known Chelsea since we were both doing 6-minute spots in the attic at The Comedy Store. I never thought she really liked me. Come to think of it...I'm still not sure." In 2009 and 2010, through his success on the show, John hit the road with The Comedians of Chelsea Lately national tour.
Also in 2010, John appropriately became the spokesperson for Edge Shave Gel during their nationwide "Anti-Irritation" campaign. In addition to his work as a comedian and spokesperson, Cap is starting to make his mark in animation. He currently voices the role of "Headphone Joe" in the Disney Channel series Fish Hooks.
