Michael Garibaldi was held captive by
evil aliens somewhere on the
Babylon 5 station. They strapped him down on a bench, while he was
kicking and screaming trying to get loose. Then they lowered a kind of
glass tank onto his head. They flipped a
switch, and a
shower of
sparks came out from somewhere inside the tank.
Then they turned it off, flipped open the glass tank, and untied him. He got up, and appeared to be completely unharmed. He talked with the aliens as if they were his old friends.
Suddenly he smiled, and then I saw it. All his teeth had become triangular fangs, arranged in such as a way that all the teeth in his upper jaw fit perfectly inbetween two teeth of the lower jaw, and vice versa. In other words, there was a cartoony zigzag line between all his teeth.
