Nurse: Okay, your finger is dislocated.. so I'm going to try to pull your finger back into place.
Brother T: Okay.. [sticks out his finger toward her]
[Nurse pulls, and brother T, blinded by the flash of pain that hit him, loses control and...]
Nurse: (immediately stops pulling the finger... pauses) Okay.. Let's try that again.
The above story demonstrates that sometimes "pull my finger" is no joke.
