In "The Sunshine Boys" by Neil Simon, the comedic team of Lewis and Clark were once the hit of Vaudeville, the times before radio and television, when people had to leave their houses to find entertainment. Comedy was quick, witty, and full of sight gags. The costumes alone caused a chuckle. So, what happened to the legendary Lewis & Clark? They split up after an appearance on the "Ed Sullivan Show", and haven't seen or spoken to each other in 11 years.
