After a lifetime of doodling on napkins, pieces of scrap paper, and barf bags on airplanes, comedian Kevin Nealon is sharing his collection of celebrity caricatures with "I Exaggerate: My Brushes With Fame," available now. Known for his time on "SNL" and "Weeds," Nealon tells Salon's Mary Elizabeth Williams why he decided to turn his self-taught hobby into something more serious. "I heard the clock ticking. I've talked about things all my life that I wanted to do, and this is something I've always wanted to do."
