With both Bugs Bunny's and Chuck Jones's Warner Bros. careers winding down, Chuck directed Bugs in the hilariously wacky short "Transylvania 6-5000" (which I recall got used in the compilation film "Daffy Duck's Quackbusters"). When Bugs arrives in Transylvania - apparently no too far away from Pittsburgh - and spots a rather Gothic castle, he decides to ask to use Count Bloodcount's telephone. While the audience can easily figure out what this guy has planned, Bugs doesn't even get the least bit scared (I bet that any other of the Looney Tunes would have died of fright upon seeing the count; see the Sylvester/Porky pairings).
But when the count puts Bugs to bed ("Rest is good for the blood.") is when the cartoon really takes off. As Bugs feels too fatty-gewed (fatigued) to sleep, he starts reading the book "Magic Words and Phrases". Much of the rest of the cartoon has Bugs in danger of getting attacked by the count, only to utter "abra-cadabra" or "hocus pocus" and change the count into a bat or vice versa! Everything that Bugs does in the second half of the cartoon just made me feel like I was going to die laughing.
It all just goes to show that there will never again be a genre like the Looney Tunes/Merrie Melodies cartoons. Up in that great nightclub in the sky, Glenn Miller must feel honored that they played off the title of one of his songs for this cartoon (actually I don't know whether or not he wrote "Pennsylvania 6-5000", but I've heard his version). There was also a silly movie "Transylvania 6-5000" starring Jeff Goldblum and Ed Begley Jr.
One more thing. I notice that this cartoon was released a week after the Kennedy assassination. I would have suspected that they would have been in no mood to release a crazy cartoon after that event, but maybe that's just me.
