My henny has a beard, as you can see. I call it a beavertail. He re-designed my site for me today, so I wrote this song about him:

Henny built a dam with his beavertail,
He built a dam with his beavertail?

Work Henny, work Henny
Build them twigs up.

Work Henny, work Henny
knock them trees down.

Henny built a dam with his beavertail.
He built a dam with his beavertail!
