|A lady went skiing and halfway down the hill had to go to the bathroom.|
No facilities nearby, she found a sheltered area, dropped her pants and proceeded to relieve herself.
Suddenly she found herself beginning to slide backwards, out into the open and down the slope with her pants around her knees. She crashed and broke her leg. The paramedics rushed her to the local hospital. The doctor walked into her room.
Laughing hysterically, he said, "You're not going to believe this, but the guy in the next room claims he fell off the ski lift and broke his leg because he saw a naked lady skiing backwards down the mountain!"
As he began to compose himself, he asked, "So, how did you break YOUR leg??"
