The Simpsons: Homer of Seville

Homer injures himself in a fall, and while in the hospital he develops the ability to sing in a beautiful, operatic voice whenever he is lying on his back. Mr. Burns overhears Homer during one of his singing sessions at the hospital and immediately hires him to sing the lead in his production of "La Bohme." Although Homer has to lie down during the performance, he wows the crowd at the Springfield Opera House. Homer becomes an enormous celebrity, especially with the ladies much to Marge's chagrin. While running from a mob of crazed fans, Homer is saved by a mysterious woman named Julia, who turns out to be a little too concerned for Homer's wellbeing.
