I see

There's a strange pressure over the knuckles of your index and middle finger. You just think it is an idiosyncratic handshake and it doesn't mean anything to you because you don't know the appropriate response. Not a Mason so the explanation I was given might be a load of rubbish and my leg was being pulled!

There's a great photo in the strath bar of the big fat ref tiny something shaking hands with John Greig before an old firm game.
