Leaky Memory

As is the case with many grandparents, Gigi and Gramps accumulated a heavily used set of toys to have on hand for when various kids dropped by.  As we sorted through boxes and cabinets and dressers and closets this past weekend cleaning out their condo, someone came across this uncommonly captivating game:

Have you played with one of these in your childhood (or yesterday)?
I remember playing this “Waterful Ring Toss” game many many times at my own grandparents house as a kid.  You squeeze the white button on the bottom, and a jet of water inside forces the rings to float about, with the purpose being to get all the rings onto pegs.
Like this:

Yeah, I rocked it.
And yeah, it leaked water down the front of my shirt while it got rocked.
Just like when I was a kid.
