Surf's Up...or is it Serve's Up?
...Okay, so the best way to invent a new game is take two games and hybridize them: say take a beach volleyball court made of loose sand and play tennis with tennis ball and racquets, but with volleyball-type rules. What would you have? Beach Tennis, the hottest new game by the water.

...Now Andre Agassi can come out of retirement and play tennis on the beach. He would love the relaxed standards of dress code.

...I guess those of us who live in landlocked states will have to come up with lakeside tennis, or sandstorm tennis, or gennis (golf played with a tennis racquet and ball). It still reminds me of Lance's game called gockey (roller hockey using a golf club and golf ball played in the hallway of your parent's house.)
