Jack's sprat could be a brat
His alewife could be mean
Each morn, with them he'd sat
And kept their fish tank clean
They spurned him in their fishy ways
They both gave Jack the moon
Of them Jack made a bouillabaisse
And ate them with a spoon

*** To the non- ichthyologists among you: Sprat: a small herring-like marine fish, Clupea spratus, of European waters; also, any of various other small fishes, mostly resembling this. Alewife: a North American fish, Pomolobus pseudoharengus, resembling a small shad but inferior as food.
