Pompous, hot-headed Italian opera singer and one-off Bugs Bunny nemesis in the classic 1949 Warner Bros. cartoon, Long-Haired Hair. This was back when "long hair music" meant classical, not classic rock. While he's trying to rehearse, Bugs ticks him off with his banjo playing, and Jones smashes it. So Bugs takes revenge later at the concert by various means, including impersonating a conductor (Leopold Stokowski) and making Jones jump through various vocal hoops.
Both Bugs and Jones were voiced by cartoon legend Mel Blanc.
