I've got two:

1. The Cat-Call

   Not quite the same level as yours, but: once I saw my cousin's cat meow at its kittens to call them for milk.

   On a spur of the moment random impulse, I meowed the same way, inadvertently replicating the mother cat's meow down to some exact degree of mimicry such that all the cats turned to look at me; the kittens stopping mid-stride to look at me for a source of milk, their confusion expressed in a footfall hesitations of whether to come to me or not.

   The mother cat meowed again, and the kittens resume their journey to her, and she threw me an irritated look.

   I have not once been able to replicate this. It was just one of those once a million moments where all the odds of the universe stacked up in favor of me, and paid out in the most realistic cat sound known to either man or cat.

2. Call to Prayer

   This one has more hidden steps: once, when I was a kid, I was bored watching endless TV coverage about the Royal family

   It was a show about the latest gossip on Princess Dianna, and there was literally nothing else to watch on another channel. So I did what any well-adjusted kid did, and that night I got down on one knee and prayed for her die. Prayed. I'm not religious nor was I raised religious in any sense.

   Anyway, one week later, she popped off. The guilt stayed with me for a while, until I decided that if God's taking messed up requests, then that's on him and not me.
