An animal that we learnt to trust
Its cunning, its planning, a must
A lot of mammals are not a fan
But look at the potential after building that dam
The river now flows to a part of ruin
Let's celebrate this genius on the wood that they've been chewing
To build a habitat for this beast of some distinction
Who has made life for others without bragging on completion
Oh, and its also what men call their wife's nunny
Strange how words switch to mean something funny!
