Harris, a budding stand$-$up comedian, spent months hanging out at Laugh Town, a local club, meeting other stand$-$ups, doing a lot of listening and finding out how they learned their trade. It got to the point where several of the star acts were trying out their new material on Harris. If Harris laughed, the material must be good, they said. Finally Harris got to the point where he wanted to try out his own act. Bobby G$,$ a successful comic, agreed to listen to Harris. Bobby laughed a few times, but as he performed his material Harris couldn't help but wonder about the odd, pained expression on Bobby's face. When it was over, Bobby told him, "Very funny, Harris. Keep working on it$."$ It was at that point that Harris decided he would become an agent for other comedians. Somehow, he knew that that was what he was truly suited for.
