Already esteemed in the Middle Ages, today more up-to-date than ever - a jester enriches every celebration in a unique manner. And yet: modern jesters are few and far between. Koller is one of the best: comedian, pantomime, actor and moderator - a man of many talents steps into the limelight. Whatever his role of the moment, Koller constantly radiates affectionate regard for his audience. He transforms your guests and customers into laughing onlookers and enthusiastic partners. The secret of his success: utterly comical characters, spirited wordplay, fascinating mastery of his body and unerring intuition about his audience. A central focus of his nimble and able improvisation consists of jocular interaction with the audience - the jointly performed play is entitled: "BE AMUSED AND AMAZED" - and everyone is capable of that!  Who lies behind the modern jester ?
