Kowalski and Olga are making love in the upstairs bedroom. Just as Kowalski is about to start up his machinery, they hear a loud banging noise downstairs.
“What’s that?” asks Olga, jumping up in bed.
“Nothing,” pants Kowalski. “Come on, let’s get on with it!”
“No! No way!” demands Olga. “No lovemaking until you find out what is going on downstairs.”
Poor Kowalski stumbles downstairs with a very large erection, and flips on the the lights. Suddenly, the cat jumps out of the window. The dog dives under the sofa. And the parrot, trapped in its cage, looks around frantically, then tucks one leg under its wing and screams, “Wait! Wait, you silly Polack… you wouldn’t fuck a cripple would you?”
