Nigger in the Wonderland

Obviously aiming for maximum offense, this game stars a racially-stereotyped caricature of a black man - whose apparent concern is the pursuit of sexual relations with a pair of (fair-skinned) buttocks. This tantalizing tooshie moves up and down the screen in evasive patterns; if our protagonist misses the mark, he will suffer a fatal meeting with the electric fence beyond.

If he does catch up with the disembodied derrière, the ensuing act is rather more bizarre than what the player is led to expect. After this, it's on to the next level, which speeds up the action some more.
