To Serve Man!
When a mysterious, lumpen-headed alien comes to earth in white shorts and sweatbands, everyone gets excited. Finally, here's someone new to challenge those top-seeded players at Wimbledon. Pundits argue as to whether he can be claimed as British, despite his vaguely Scottish accent. The popular vote is yes, unless he loses, in which case the Scots can have him.
Our tall, lumpy champion battles his way through the early rounds, until he finally makes it into the final, against Djockavic himself. It's a tense, nail-biting seven hour match. Both show no sign of flagging. How can this stalemate be broken?
The alien reaches into his sports bag following the cry of "new balls please". And the true meaning of his claims "to serve man at tennis" are revealed. He hurls a human head high into the sky and smashes it across the net. It's the head of a player he beat in the previous round. The audience screams. Djocovic misses. The pundits begin egging on this plucky Brit. Head after bloody head are volleyed back and forth at great speed.
It's game, set and match, in the Twilight Zone...
