A Drive line.
For those of you not familiar with a drive line is, I will tell you.
When you are driving down the street and pass a really tall pickup truck,
its that long cylindrical thingy that is spinning like crazy under the truck.
It is big, heavy, and made of metal.
And here is what happens when you are laying underneath it
and it decides to fall.
Two very broken front teeth.
That black on the edge of one of the teeth is
actually drive line grease (yum).
BUT....... if you are lucky enough to have a dentist handy, who
knows how to deal with drive line tooth fractures, you could end up
looking like this.
The teeth will always be a tad weaker then they were before being
crushed by the spinny thingy but they will do much better then
snaggle toothed alternative.
