it's my life

A young artist works in his studio at home. He specialises in nudes, and has been working
on a masterpiece for several months.
His model shows up and, after exchanging the usual greetings and small talk, she begins
to undress for the day's work. He says, “Don’t bother undressing. I don’t feel like
painting. I think I’m getting the flu. I’ll pay you for the day. But you can go home. All I
want to do is have some hot soup and then go to bed.”
The model says, “Hey, I’ll fix the soup for you. It's the least I can do.”
They’re sitting in the living room exchanging small talk and enjoying a cup of soup, when
the artist hears the front door open and close.
”Oh my god!” he whispers, “It's the wife! Quick! Take all your clothes off!”
