Clothes off !
There was an artist who worked from a studio in his home. He specialized in nudes, and had been working on what he thought would be a masterpiece for several months now.
His model showed up and, after exchanging the usual greetings and small talk, she began to undress for the day`s work.
He told her not to bother, since he felt pretty bad with a cold he had been fighting. He added that he would pay her for the day, but that she could just go home; he just wanted some hot tea and then, off to bed.
The model said, "Oh, please, let me fix it for you. It`s the least I can do.""Oh my God!" he whispered loudly, "It`s my wife! Quick! Take all your clothes off!"
