The lovely Smeagol, aka Gollum, from The Lord of the Rings trilogy, feeds on fish. He fishes by hand as a poacher (but there are few fishing guards at the Forbidden Pool) while humming his famous song:
♫ ♫ We only wish
To catch a fish,
So juicy-sweet!♫ ♫
And now the truth : The notorious My Precious is not a ring but a carp !
