Vernon was once a trumpet player and often carried a cornet with him as a prop during his stand-up routines. As with Henny Youngman and his violin, it was seldom actually played. When he guested on a summer variety program hosted by Al Hirt in 1965, he came on with his cornet and said, "I play like I'm Hirt." He was a popular figure on "The Ed Sullivan Show" and other variety shows, where he often ended his act by blowing a cornet and saying, "I think I hurt myself!"
