What, not like steak and kidney pie, why I never! Of course when I once asked my ex to make it for me she said “How do you cook kidneys?” Upset her no end when I replied “Put them in a pot and boil the piss out of them.”

I can’t stand the taste or smell of liver.  My wife loves it, too.  I tell her that is great that some like it, otherwise the world would be filled with rotting green liver. Reminds me of cooking kidneys.  How do you cook kidneys?  Well, you just boil the pi** out of them.
