As Fate would have it, he has since put that knowledge to good use. As of this year, he learned how to hoist himself up on the railing of a fenced in area around his dog house, balance on the railing, and then jump down on the other side. It is no small feat for him to do that. The first time must have been the hardest because of how he had to position himself just right to make it work, but now, he has it down.
I am amused and amazed at his having figured this out and truly suspect he learned a thing or two during those hours of watching the gymnasts. So all of you reading this that have furry members of your family, be warned. Our furry friends are gaining on us. They are a lot smarter than they have been given credit for. I think they have wanted their cognitive abilities to be a secret. In the case of Ridley, his cover is blown. I knew from day one he was a thinker. Never mind the squeaky toys. He wanted a chess board.
