Of halibuts and their enemies

I read an interesting thing in the paper the other day," said Lord Tidmouth. "It appears that the sardine's worst enemy is the halibut, and I give you my word that until I read it I didn't know the sardine had an enemy. And I don't mind telling you that my opinion of the halibut has gone down considerably. Very considerably. Fancy anything want to bully a sardine. I mean to say!"
