Was strobing a 206 tailrotor some years ago. Heli was at 100% and flat pitch and I was about 10-15 feet away from the T/R. While tuning the chadwick in, a shadow appeared over my shoulder, looked up and there was the pilot who was supposed to be in the cockpit running the bloody thing!
With a big grin he asked, "how's it looking?"
I quickly walked away until he got the hint.
