Lizzie Tizzy

Beleaguered NYC celebrity publicist Lizzie Grubman -- who injured 16 people with her SUV outside a Southampton, N.Y., nightclub July 7 -- has inspired a game that's sweeping the Internet nation. In ''Lizzie's Hamptons 500'' (geocities.com/mercfilms/index.html) players hit exiting clubgoers with a Mercedes SUV driven by a booze-guzzling Grubman. Why the glee? ''Lizzie Grubman represents your typical snob -- that person that thinks that they own the world and everyone's beneath them,'' says a New York City radio personality (who wishes to remain nameless) who is peddling T-shirts commemorating the accident on hitandrunbitch.com. ''People are just getting a kick out of this.''
