Which one is it?
A.) What comes around, goes around.
Or…
B.) What goes around, comes around.
Karma is not a bumper sticker. The concept is much more complex than that.
Nice reply, even if it does lose you Karmaic points. 
I would probably pick B. That phrasing reinforces the notion that karma starts with your own actions ‘going’ out into the world, and then the impact of those actions, the good or the bad, ‘come’ back to your own life.
Yeah. “comes aroud, goes around” is childish. It absolves the sayer of personal responsibility for their own actions.
Round and round
With love we’ll find a way just give it time
How about “As you sow, so shall you reap”?

Definitely “What goes around, comes around.” The other way makes no sense.
My Karma ran over your Dogma.
“What goes around comes around” is an admonishment to good behavior.
“What comes around goes around” is a threat.
Neither needs a comma.
Stop that! Or I’ll have to give you such a pinch!
That would make a great bumper sticker.
What comma round, Goa round.
No, I have no idea what that means.
Consider it carefully and you may yet be ready for the next koan.
I’m ready for the Koan Of Silence at this point.
It’s summertime, so I am going for an I Scream Koan later.
Either way. It’s imaginary so it can mean whatever you want it to mean.
I believe the philosopher and thinker Homer* said it best…
“You can’t sell it! Karma can only be portioned out by the cosmos.”
*Simpson
I was thinking of that scene in connection with this thread too! IMHO Homer was confusing logical levels in this context. (As he so often does. 
) Apu wasn’t actually trying to sell Homer karma, he just wanted Homer to ‘buy into’ the concept of karma so Homer would understand why Apu needed to do him a good deed.
