The theme was "Combine two pictures of the same person from different time periods."
Some are perfectly executed, like the Harrison Ford one.
Some demonstrate creativity in the theme, like mixing Obi-wan from Episodes I and IV, or 1st season/later season Bart Simpson, Mars Face 1976/2001 and Seabiscuit/Elmer's.
Some are pleasantly bizarre like Dali and John Paul Jones.
Some are the usual stupid, cruel and naughty things one expects from fark.
