 One of Barber's more popular routines involves "Diva," a female dummy which appears to be operated by Seville (with Barber on the other side), with all three engaged in an operatic song from "The Barber of Seville" — part of the pun from which the name of Barber's act, "Jim Barber and Seville," is taken.Barber has been named "Ventriloquist of the Year" in 2006 by the International Magicians Society, "Ventriloquist of the Year" in 1984 by the Vent Haven International Ventriloquist ConVENTion, "Comedy Entertainer of the Year" by the National Association of Campus Activities, and one of the "Funniest People in America" by Showtime/The Movie Channel for his technical vocal skills and creative approach.He was featured in a performance during "Ventriloquist Week" on February 15, 2007 on the "Late Show with David Letterman" which aired again that April.
