RETURN TO TENDER: Bruce Willis is moonlighting again. On a recent visit to Chicago’s Planet Hollywood, the actor and former bartender jumped behind the bar and began taking orders. ”People were doing double takes like ‘Is that really him?”’ says a waitress who helped Willis dole out rounds of Die Hards (Rum, blue Curacao, and pineapple juice). ”We’re not sure how many drinks he gave away, but we were packed,” says a restaurant spokeswoman, adding that Willis-a Planet Hollywood investor-has mixed drinks at the Manhattan locale, too. Later, Willis made a hit with the staff by telling the crowd, ”Now that you all had a drink, reach into your pockets and tip the help.” Says the waitress: ”People began throwing dollars. There must have been over $100, and he left it all for us.” What a guy. -Cindy Pearlman SMITH & LESSOns: TV’s Will Smith (The Fresh Prince of Bel-Air) could have guessed that playing the role of a philosophizing con man in this month’s Six Degrees of Separation would be educational. But he didn’t realize just how much he would learn. After Smith landed the part, director Fred Schepisi insisted that he take acting lessons as well as speech and diction classes before a single scene of the film was shot. ”Will has a reputation and a name,” says Schepisi. ”(But) this was a work of more substance. We weren’t expecting to teach him about the whole acting experience, but we wanted him to have a healthy respect for what’s involved.” According to Smith’s spokesman, the actor was an eager student. ”He wanted to be as prepared as possible.” -Rebecca Ascher-Walsh

BARNEY’S NEW SUIT: What’s Barney’s latest tune? ”I sue you, you sue me.” The Lyons Group, which represents the popular purple dinosaur, is threatening legal action against the New York branch of Jews for Jesus, a religious organization that’s been using the prehistoric one’s image in a recruitment campaign. ”Barney is specifically designed not to favor any organization,” says the dino’s mouthpiece Beth Ryan. Jews for Jesus declined comment. -Casey Davidson

chewing the scenery: Before director Jonathan Kaplan started shooting Twentieth Century Fox’s Bad Girls ( 183, Aug. 13), he rounded up the film’s stars-Madeleine Stowe, Drew Barrymore, Andie MacDowell, and Mary Stuart Masterson-for ”what we called cowboy camp,” reports Kaplan. ”They spent all day, every day, for three weeks taking riding and shooting lessons.” But it was Stowe who took her training above and beyond. ”Madeleine also learned to chew tobacco,” he says, ”even though her character doesn’t.” So why study conduct so unbecoming? Kaplan explains: ”There’s an expression rodeo cowboys have, ‘Cowboy up.’ It means be macho, toughen up, take the blows, and don’t complain. Madeleine chewed tobacco to help herself ‘cowboy up.’ It’s the first time I’ve ever heard of an actress using chewing tobacco to get into a role. I don’t know how I feel about that.” -Stacy Jenel Smith

Party, Off: Add Nirvana to the select few who have seen Paramount’s Wayne’s World 2, opening Dec. 10. Hoping that the grunge stars would make a cameo in the movie, the band was sent a copy of the sequel when they were playing in Chicago last month. A band spokesman says Kurt Cobain, Krist Novoselic, and Dave Grohl screened the movie in their hotel room, but they have yet to air their opinions. ”I call them and they say stuff like ‘We’re sleeping,”’ he says. Although it’s unclear why the band declined to appear, the spokesman did note that Nirvana has already helped out two other burnouts: They contributed a song to the Beavis and Butt-head album. ”Nirvana really likes Beavis and Butt-head. I’m not sure (about) Wayne’s World.” Paramount had no comment. -CP
