Steve Carell was on The Late Late Show and half century old Craig Ferguson told the 49 year what is one of the worst things to happen to you when you turn 50…colonoscopies. Then the two funny men went on and on about the experience until they finally talked about how they have to blow air up your rear. At the point the conversation went to a place that got the CBS late night host to admit he actually made himself laugh. And let me tell you what he is so funny that I promise I am not blowing smoke up your a$$ when I tell you you will laugh and laugh.
