What did the baritone say to the alto?
Nothing, you couldn’t hear him.
Hey, listen up, buttercup. This joke is about singers, see? A baritone is a dude singer with a low voice, and an alto is a chick singer with a high voice. The joke is that you can't hear the baritone, cause, like, his voice is too low. You probably can't hear anything, with those big ol' ears of yours.
