That photo reminds me of a guy I knew years ago. Really nice guy with a ka-zillion college degrees. He was "smart" but had absolutely no common sense.

One day I walked up to him and he was trying to take the back off a transistor radio with a little pocket knife. An older friend with no formal education but LOTS of sense witnessed the whole thing.

He laughed and got a phillips head screw driver for the guy and said, "You know, he could probably take that radio apart and put it back together again. But he doesn't have enough sense to get the back off."
