Bugs Bunny Show Episode 147 - What's Opera, Doc Episode Title:What's Opera, Doc.Episode Description:The screen pans on the silhouette of a mighty Viking arousing ferocious lightning storms, but then zooms in to reveal Elmer Fudd in armor (as the demigod Siegfried). Elmer sings his signature line "Be vewy qwiet, I'm hunting wabbits" in "wecitative" (recitative), before he finds "wabbit twacks" (rabbit tracks) and arrives at Bugs Bunny's hole. Elmer then jams his spear into Bugs' hole to "Kill the wabbit! Kill the wabbit! Kill the wabbit!" Bugs sticks his head out of another rabbit hole and, appalled, sings his signature line "What's up, doc?" to the theme of Siegfried's horn call from the Ring Cycle.

At that, Bugs flees, Elmer realizes "That was the wabbit!", and the chase begins...
