Probability of this happening is so low, that we'll not likely see it again.

[Drive-By-Shooter]

I had been taking flower close ups using the pop-up and a second hand held flash optically coupled with Nikon's CLS. My wife was walking towards me and I took a quick pic of her with both flashes. I didn't know she was about to shoot me. Unbelievably, she clicked at the same time!
What I find intriguing, is that her camera apparently saw the preflashes and adjusted the exposure. Those flashes were dimmer than what went off in the pic. The flowers and deep shadows are darker than expected had there been no influence from my flashes.
Anyone else ever seen such a coincidence of a shot within the 1/100 second that another was taken?
