Where do all good Christians go on Sunday? To Our Favorite Starbucks, of course. Actor Christian Slater made the scene at 7th and Montana this morning and wasted no time ordering-up a latte. Perhaps he was licking his wounds from the recent cancellation of his NBC-TV show, My Own Worst Enemy, which lasted for only nine episodes and was panned by critics as "a clunky secret agent mess masquerading as a morality play." Speaking of which, Actor-Barista Tyler proved that he, too, can be his own worst enemy today when he introduced the crowd to his latest "co-star." "Look," he said, trying to steal the limelight from Christian Slater, "My new co-star is a snail!" And with that, he plucked a snail out of the flower bed on 7th Street and waved it in front of my face. Tyler will appear on the NBC-TV supernatural thriller, Medium, on June 1. As for the snail, I understand it's playing an exclusive engagement tonight -- for "one night only" -- at Cafe Bizou in Sherman Oaks. Now that's what I call "Dinner Theater" ...!
