when did mister b decide

When did Mister B decide
That he was thru with his old neck
And make with just a piece of rope
His head and body to connect?

When you have a neck of rope
It’s hard to keep your head up straight
It’s best to lie down in a box
Stay very still, and meditate

On why a neck of rope is so
Much better than a neck of bone.
Because you made a neck of rope
The rest of us have heads of stone
