Well played. Oldest trick in the TEACH YOUR GRANDSON PING PONG book.

That is such a hard thing to do, of course not just this expert/perfect thing, but just that genre of serve in general.

I could never do it well.

this only succeeded because the other dude looks really high

I must've watched that a few dozen times and am still not sure how that ball is served. I'd love to see how this is actually done from a better perspective maybe.

I'm confused; did his paddle actually touch the ball or did he just--spin or bump it with his body across the net? and how is that a legal serve?

Sorry, need to see it in higher def and from multiple angles

Oh the marvels of internets.

It's apparently backspin:
