Circa 1948. An opera singer named Giovanni Jones gets annoyed at Bugs for playing his banjo, harp and tuba and therefore distracting him from his singing practice. However, rather than politely ask Bugs to stop playing during his rehearsals, he uses the instruments as weapons to hit Bugs. He is initially tolerant of the singer's apparent rudeness, taking the first two attacks in stride; but after a third instance of such brutality, Bugs faces the audience and declares his time-honored, Groucho Marx-inspired warning: "Of course you know, this means war!"
