What is the funniest random incident you've ever seen or had happen to you that can make you laugh by just recalling it?

What is the most amusing and unexpected incident or accident you’ve ever witnessed or been involved in? Nothing where someone was badly hurt, please. Just random, funny, weird or silly, that still has the power to crack you up whenever you think about it, no matter how long ago it happened. One of those things you wish you had on film (or maybe do).

I have two to begin with:

Years ago when walking in the pouring rain to my garage after work, I passed the entrance of a men’s store where a man was about to open his umbrella and step out from under the awning. As I got just to him, he hit the button on the umbrella and, instead of opening, the top portion shot (still closed) off the end of the stick like a rocket and landed at my feet. I lost it.

The other: Playing Frisbee in the backyard with my brother years ago, he threw the Frisbee far to one side and I had to pass behind a tall shrubbery to catch it. I emerged from the other side just in time for the Frisbee to make a perfect landing on my head.
