When we ordered the pool table for the office, we also bought a ping pong topper so we could use it as a conference table. I hadn’t actually played ping pong since college and forgot most of the rules (more at Wikipedia). Late last week, we set up the net and it’s been non-stop ping pong during break times since then. It takes more skill and physical effort than I remember, so not only is it fun, it’s good for you!
