I Can't Kvetch

A Jewish man in a hospital tells the doctor he wants to be transferred to a different hospital. The doctor says "What's wrong? Is it the food?" "No, the food is fine. I can't kvetch." "Is it the room?" "No, the room is fine. I can't kvetch." "Is it the staff?" "No, everyone on the staff is fine. I can't kvetch." "Then why do you want to be transferred?" "I can't kvetch!"
