Heckler! chronicles the odyssey of comedian Bobby Kelton, who morphed from a shy kid growing up on Long Island, New York, to a comedy star on "The Tonight Show " and at Caesars Palace.

From the intimate comedy clubs in New York and Los Angeles to the big-time stages of Las Vegas, Bobby's stories of hecklers, stage-rushers and unexpected showstoppers prove how tough it is to be a stand-up comedian. He shares behind-the-scenes tales from backstage at "The Tonight Show," touring with Tom Jones, trading barbs with Mickey Mantle, causing havoc with Larry David, and accidentally flattening Gladys Knight during a tennis match with her Pips: "If she had been really angry with me, I easily could have ended up on a midnight train to Georgia."

Heckler! is a funny and poignant look at a comedian's journey and the ups and downs of making people laugh for a living.
