Common sense and a sense of humor are the same thing, moving at different speeds. A sense of humor is just common sense, dancing.
I heard something funny on the radio the other day. I don't remember who I was listening to, but it was a man. A man who was talking about his Boxers (dog) and how he has acquired his dogs through a Boxer rescue, but the last dog he bought from a breeder. He wanted the dog, but was reluctant about the price. He had picked a male, so the breeder offered an incentive to buy, a $50.00 reduction in price to neuter the dog. In his droll voice he recounted his wife's comment. "Now we know what they're actually worth." Badda Bing!
