Tongue twister joke

A Lama came to the east with a bag of frogs in his hand, and a mute came to the west with a horn pinned to his waist. The Lama wants to exchange the frog for the horn pinned to his waist, but he doesn't want to exchange the horn for the frog's mute on the Lama's back. The Lama was so anxious that he picked up the frog in his hand and hit the dumb with the other horn. I know nothing about horns. The Lama who raised the frog hit the mute who didn't talk to the frog. I know nothing about frogs. The dumb man who can't speak with horns hit the Lama who raised frogs with horns. The Lama who keeps frogs goes home to stew frogs. The dumb man who didn't speak stood there playing the trumpet.
