This is medical video of Frank Kramer (from the Frosty, Heidi, and Frank radio show in Los Angeles) inside his throat looking at his vocal chord. For several months in 2008 his voice was getting stranger and stranger. Finally he went in to this doctor and he found what you see in this video.
The vocal chord looks like a floating ping alien waving open and closed and the big white ball of a polyp is unmistakable and causing an obstruction when Frank attempts to speak. It was surgically removed and he couldn't speak for two weeks after the surgery, but now his voice is back to normal and the polyp was non-cancerous.
