You've got a pet halibut?

I am not a looney! Why should I be tied with the epithet looney merely because I have a pet halibut? I've heard tell that Sir Gerald Nabarro has a pet prawn called Simon and you wouldn't call him a looney; furthermore, Dawn Palethorpe, the lady show-jumper, had a clam, called Stafford, after the late Chancellor, Alan Bullock has two pikes, both called Chris, and Marcel Proust had an haddock! So, if you're calling the author of 'A la recherche du temps perdu' a looney, I shall have to ask you to step outside!

So now I know who John Cleese is refering to in that sketch.
