Q) What are common sense's. (A) Sense's we all share, (we) being Human's, Man and Mankind.
Q) How many are there (A) 5, (1) Sight (2) Hearing (3) Smell (4) Taste (5) Touch.
So... this poster relies on his five common sense's to inform himself of his environment, relinquishing critical thought and the power to choose along the way .
In practise he equates his abilities to that of a dog as that is precisely what dog's do, being animated and fully subjected to their environment, absent of choice or critical thought and reliant solely on common sense's

Worse still for this particular poster as he now finds himself at a clear disadvantage, as dog's have a greater range of (1) Sight (2) Hearing, (3) Smell and (4) Taste, as well as greater physical stamina and a superior digestive system

To further highlight the inefficiency in this posters method of problem solving and common sense, I highlight all the LBW's/ home runs/ goals etc he didn't agree with, until he was proven wrong by the slow motion replay
