Apparently the trick for roller coasters is to keep the passengers hearts in the same plane so they don't perceive the ride as jerky.

Unless you are in Poland; then you need to keep the Poles in the right-hand plane or it will be unstable.

I thought the Poles needed to be either all on the left-hand plane, or within the unit disk, for stability? (I haven't had my coffee yet, so maybe I'm remembering wrong).

Either way, I loved the joke. Thank you!

You are right, I wrote that before having my coffee...
