The Man from Chernobyl.

Sifis is fed up with the smog in central Athens and decides with his family to move to the countryside to get some fresh air. But there, he gets hit by radiation from the Chornobyl nuclear reactor leak. When he decides to return to Athens to buy supplies, the side effects of the radiation begin to take effect, and not only does his hair fall out and he becomes bald, but he also becomes a laughing stock because of a tail that grows out of his backside.
