Blue Collar Comedy is a hugely successful genre of stand-up made popular by comedians Jeff Foxworthy, Larry the Cable Guy, Ron White and Bill Envall, all of whom toured as part of the Blue Collar Comedy Tour. Named for "blue collar" work, the Blue Collar comedians position themselves as very much working-class and of the people (this despite the fact that they've all gone on to become millionaires). Most of the humor invokes a Southern sensibility (with jokes about what it's like to live in the South -- such as Foxworthy's famous "You might be a redneck..." routine -- or the way it influences your view of America) and most of which (save for White) is mostly "family-friendly". Though heavy on innuendo, most of the Blue Collar Comedians avoid working blue.
Blue Collar comedy has surpassed its genre and gone on to become a successful brand name, inspiring spin-off projects like the the Blue Collar TV sketch show on the WB, the Blue Collar Radio comedy channel on SIRIUS/XM Satellite Radio and even a second wave of Blue Collar comedians, billed as "Blue Collar Comedy Tour: The Next Generation."
