This is an awesome post - you just bought my childhood flooding back to me!! I completely forgot about the water ring toss, but I was immediately transferred back to my room, where I would spend hours trying to get those confounded rings on those little plastic pegs.

I remember putting a couple of drops of detergent in there to make them even more slippery, and thus, more difficult each time my sister wanted a turn!!

Thanks for this little slice of nostalgia.
