A cyclist is commuting to work -- the morning is
beautiful and he's looking forward to getting out on one
of his favorite roads. Unfortunately on his way into
town, an [censored] motorist cuts sharply in front of him to
pull into a left-turn lane, and only the cyclist's skill
and years of experience keep him from losing control and
dumping the bike, and he finally manages to wrestle his
ride to a safe stop.
[censored] to the max, he spies a large rock in the gutter,
picks it up and throws it with all his considerable might.
It smashes through the rear window of the car and whacks the
driver on the back of the head, knocking him out. The
vehicle loses control and eventually smashes into a phone
pole -- the car is totalled and the driver is put into
hospital for weeks.
Some time later at his trial, the prosecuting attorney is
cross-examining the cyclist on the stand and finally just
asks "WHY?! Why did you do it?!"
The cyclist thinks for a moment, then starts beaming and
says "I didn't see him!"
