Pirate Captain Jim Shel Silverstein

"Walk the plank," says Pirate Jim.
"But Captain Jim, I cannot swim."
"Then you must steer us through the gale."
"But Captain Jim, I cannot sail."
"Then down with the galley slaves you go."
"But Captain Jim, I cannot row."
"Then you must be the pirate's clerk."
"But Captain Jim, I cannot work."
"Then a pirate captain you must be."
"Thank you, Jim," says Captain Me.
