Sense Sonnet - Pumper

Super Pen

Samuel Clemens used pen names
Before deciding on "Mark Twain."
He would sign "Josh" to sketching frames,
And "Snodgrass" to lettered refrain.
Mississippi riverboating
Gave Samuel the Mark Twain choice.
When shouted it meant just one thing,
"Safe to pass," from a boatman's voice.
So famous Mark Twain came to be.
Did he live up to its truth told?
In reply he would say that he
Was too modest to talk so bold.

Whatever name, one thing is sure,
He left us great literature.
