Q: What runs but never walks, murmurs, but never talks, has a bed but never sleeps, and has a mouth but never eats?
A: A river!

Explanation: Thanks the Instagram account of Glacier National Park for this week’s joke. 

There are many words in English that have multiple meanings and this joke shows us many of them that are related to a river.  The water in a river runs.  The river murmurs by making noise as it flows to the sea.  The bed of the river is the ground that is under the river.  The mouth of the river is where the river flows into the ocean.

This joke is funny because it uses many words related to river that have multiple meanings.

Are you familiar with Colombia’s Rainbow River?
