A man walks into a restaurant and orders squid.
"Certainly Sir," says Gervaise the waiter, "Would you like to choose your squid from the tank over there?"
"I'll have that little green one with the moustache" says the customer.
"Oh no!" replies Gervaise "but he's my favourite! He's so small and cute and friendly. Surely you'd prefer one of the bigger, meatier ones?"
"No" says the customer "It's got to be that one."
So Gervaise gets the little green squid out and puts him on the chopping block, raises his knife and ... the little squid looks up and smiles, twitching his bushy moustache into a big friendly grin!
"It's no good", says Gervaise, "I can't do it. I'll have to ask Hans who does the washing up. He's a big, tough brute - he'll be able to do the evil deed."
So out comes Hans, while Gervaise disappears off in tears. Hans picks up the knife, raises it to chop the little squid's head off and... once again the little friendly squid looks up and smiles, wiggling his little legs and twitching his little moustache. So Hans, too, finds it impossible to kill him.
Hans that does dishes is as soft as Gervaise with mild green hairy-lip squid.
