The "personalized" basketball example isn't a good one - your hand pushing the ball down and the floor pushing it back up aren't an action/reaction pair. You could, for example, push the ball down over a bottomless pit (or in space or whatever) so that you have one without the other. Nitpicky, yes, and it also seems plausible that this very example would be found in textbooks already, but I wouldn't like to use it.

Nor do I understand why you'd say "ouch, that hurt" while dribbling...
