Working on the air in radio, which is a one dimensional audio medium, the screw ups are usually minimal.  I might mess up a word or sentence now and then, or foget to bleep out an "F" bomb as you know I have on the occasional 'WTF Friday", but working in TV is a different story.   Being both Aural and visual there is at least twice the opportunity for things to go south.  I think you'll see some great, and funny ass examples of that in the accompanying video.   After vfiewing this, you're less likely to be critical of Brad Byrd or Wayne Hart when they make a little mistake!
