{Comedians who make you think}

If you're looking for those comedians who make you laugh about things in life that would otherwise make you bitter and sad, then look no further. These four lads are probably the greatest comedians for shining a positive light on negative situations. They also make you think about what's going on in the world culturally, politically, environmentally, etc. It's stuff like this that helps me smile even through the bad times. :)
