Teppo Tampereella

In a mental institution a nurse walks into a room and sees a Turkulainen patient acting like hes driving a car.
The nurse asks him, "Teppo, what are you doing?"
Teppo replies, "Driving to Tampere!"
The nurse wishes him a good trip and leaves the room.
The next day the nurse enters Teppo's room just as he stops driving his imaginary car and asks,
"Well, Teppo, how are you doing?"
Teppo says, "I just got into Tampere." "Great," replies the nurse.
The nurse leaves Teppo's room and goes across the hall into Matti's room, and finds Matti sitting on his bed furiously masturbating.
Shocked, she asks, "Matti, what are you doing?"
Matti says, "Im screwing Teppo's wife while hes in Tampere"
