Not for these daring performers.

The Rebels Without Applause improv and comedy troupe members simply make up much of their shows.

"When something goes off and the audience goes wild, it's a great thrill," said Scott Arkin, 15, of Coral Springs.

For improvisation segments, the audience gets to suggest characters or subjects. The ideas have included a restaurant waiter serving messy eaters and putting a science fiction slant to a scene with someone trying on glasses.

Beavis and Butt-head have been requested, and so has The Love Boat.

Marc Rothchild, 16, of Hollywood, was told to be a guy who thought he was plastic food wrap at a party. During the skit, he rolled in and asked the party-giver for leftovers.

The skits are filled with adlibs and slapstick. Each show is an original, guided by the audience's imagination.

"To me, it's the greatest feeling to be out there either doing stand-up or improv. Either way it feels terrific," said Flip Schultz, a college student from Plantation.

Schultz is among 10 teen-agers and young adults in the troupe, formed in November, and part of the Plantation Theatre Company.

"It's a different venue for actors," said the theater's president, Floren Lefebvre. "It sharpens their acting and reaction skills."

The shows are informal adn sometimes silly.

Even so, the performers must focus on classic acting skills, such as staying in character and projecting their voices for those in the back, said director Gary Wayne.

The audience members say they like the spontaneity adn the chance to call out ideas.

"It's complete and utter fun," said Nina Docoteau, 20, of Sunrise. "I enjoyed the show completely. It's something I would love to do myself."

Bobby Rogers of Sunrise also gave the show a favorable review.

"It's better than going out and getting drunk on Friday. It's a lot funnier," he said.

"I just sat there and laughed the whole time," said Jaclyn Corr of Pembroke Pines. "It was so hilarious.

Sometimes the audience is so enthralled they become part of the show.

"I thought it was something I could do, and I guess I can or else they would have kicked me out by now," said Charlie Brennan, 20, a college student from Sunrise.

"I'm doing it just because I have a blast doing it," he said.
