The similarities between this pair of "ginger goblins" are pretty alarming. Besides the fiery red bowl cuts and milky white complexions, both Mark Davis and Sam McKinney came onto the scene at the tail end of great runs. Al's inexplicable son Mark took on a more clammy hands approach in the final months before his father's passing, while young Sam represented Diff'rent Strokes' last-ditch effort to save the show. Diff'rent Strokes failed, while the jury is still out on the Raaaaidahs.
On a side note, we officially have way too much time on our hands.
