Long-Haired Hare

One day, Bugs is sitting outside his hole, playing a banjo and singing "A Rainy Night in Rio". Nearby, in a luxurious house, a famous opera singer named Giovanni Jones is rehearsing "Largo al factotum" from The Barber of Seville. However, Jones is distracted by Bugs' singing, and goes over and smashes his banjo over his head in a fit of anger. Bugs remarks, "Music hater."Later, Jones is rehearsing again, but is again distracted by Bugs playing the harp and singing "My Gal is a High Born Lady" (with re-written lyrics). Jones destroys the harp and jams Bugs' head in it, causing him to remark, "Also a rabbit hater. Oh, well." Bugs then decides to loudly play the tuba, but this does not impress Jones any more than previously. He ties Bugs' ears to a tree and beats his head against the branch. Fed up, Bugs makes his trademark Groucho Marx comment: "Of course you know, dis means war!"That night, Jones is performing a concert at the Hollywood Bowl, and begins by singing "Chi mi frena in tal momento". Bugs is sitting on top of the large stadium, and taps it with his fingers, the reverberation causing Jones to tremble slightly when he hits a certain note in the song. Bugs remarks, "Acoustically perfect," and bangs on the stadium with a mallet, resulting in a much more violent reverberation & causing Jones to wildly shake and move around the stage, until he falls into a tuba player's instrument. Bugs takes Jones back stage, informing the audience of an interruption in the program, and orders the maestro to play a vamp. Bugs fixes Jones up backstage, and sprays liquid alum into his mouth. Jones goes back on stage and proceeds to sing the "Figaro" section of "Largo al factotum". With each singing of "Figaro", his head shrinks to an extremely small size and his voice grows extremely high in pitch.Later, Jones is due to go on stage again, but Bugs, dressed in a bobby soxer outfit, begs him to stop. Bugs showers Jones with praise, and asks for his autograph, giving him a pen which turns out to be a stick of dynamite. It explodes as Bugs sneaks away, and Jones steps onto stage, bows and faints.Finally, Bugs enters disguised as famous conductor Leopold Stokowski. Greatly in awe, all the orchestra members, Jones and the conductor immediately stop what they are doing, so Bugs can take over. He snaps the conductor's baton in half, and proceeds to conduct Jones through a bizarre performance with his hands. He receives rapturous applause, but Bugs is not finished. He then persuades Jones to hold a high note for an extremely long period of time. While Jones is holding the note, his clothes unravel and his face changes from one colour to another. Bugs slips his hand out of his glove for a brief period, and steps outside to order a pair of earmuffs, which he puts on to block out the noise. He returns to find Jones still holding the high note and pounding on the floor, but continues to have him hold the note. Eventually, this causes the Hollywood Bowl's dome to crack and fall apart. The debris crashes onto the stage, burying Jones.Bugs receives massive applause, and bows to the audience. The ravaged Jones also emerges from the rubble and bows. Just then, Bugs notices a large boulder suspended on a rafter. He gets Jones to hold the high note again, as the boulder tumbles off the rafter and hits Jones, finishing him off. Bugs then pulls out his repaired banjo, and plays "Good Evening, Friends". Iris out.
