Alex Karras' kidneys have failed. Given only a few days. While he rose to fame as a tackle for the Detroit Lions....many of us born in the 70s and 80s know him better for a certain movie he appeared in. And also for having his and his wife's pet TV project royally railroaded by the ABC network trying to cash in on the popularity of "Diff'rent Strokes". Three guesses as to which character was not part of the original pitch.
