A Penguin.

The Pen-guin sits up-on the shore And loves the lit-tle fish to bore; He has one en-er-vat-ing joke That would a very Saint pro-voke: "The Pen-guin's might-i-er than the Sword-fish"; He tells this dai-ly to the bored fish, Un-til they are so weak, they float With-out re-sis-tance down his throat.
