Bugs demonstrates how to handle a pesky vampire with six simple magic incantations . The title is a pun on " Pennsylvania 6-5000 " , a song associated with Glenn Miller and referring to the now-archaic system of telephone exchange names where the first two characters of a telephone number were expressed as letters : " Transylvania 6-5000 " stands for " TR 6-5000 " which devolves to 876-5000 . This cartoon also released 8 days after president John F. Kennedy was assassinated in Dallas , Texas
