I've forgotten about plenty of situations where things could've gone wrong but didn't but I can still vividly remember accidentally hitting myself in the dick with my bike handle.
(Since I know someone will want to know: I misjudged my speed and the impact a wet wheel had on my braking power. When I noticed I was going too fast to take a corner I braked and the front brake locked the wheel immediately. Inertia did the rest.)
That and a (thankfully merely scary) run-in with aquaplaning a few years later taught me to be wary of wet driving conditions, especially of braking in them.
