Short answer, yes.
Longer answer, several, none particularly horrible.
One of the incidents I got tired of describing what happened until I came up with this. It is the truth, the whole truth, and nothing but the truth.
While conducting an impromptu experiment on the friction coefficient of limerock mud, I experienced a brief period of free-fall interrupted by a collision with a celestial object at 32 feet per second (975 centimeters per second). The vector of forces involved in this collision focused on the right olecranon process resulting in a catastrophic structural integrity failure.
But, I'm much better now.
