How many quacks does a quack quack quack
before he ducks for fish?
How many ducks does a quack quack duck
before his fish is fished?

How many geese's goose is cooked
because they ate up all the fish?
How many cooks cook geese
before their goose is cooked?

How many fowl fall foul
of fowl hunting cooks?
How many fowls' geese are cooked
before they flew from a foul hunting cook?

How many ducks' goose is cooked
because he didn't duck duck duck
when a fowl cook reached for his neck?
