Joe and others seem to have covered almost anything I could add about one meatball and one fishball, except a parody verse of "After the Ball was Over" from READ 'EM AND WEEP:

After the ball is over, Mary takes out her glass eye,
Puts her false teeth in cold water, corks up her bottle of dye,
Throws her cork leg in the corner, hangs up her wig on the wall,
Then what is left goes to by-low, after the ball.
