The one fine day of summer 2016 happened yesterday. The downside to this hot weather is the onslaught of flies.
A grandmother was failing miserably to swat some pesky flies. She handed the fly swat to her little 5 year old grand daughter.
"Here Pet. You've more energy than me. You try to get them."
The little girl took the implement and began chasing around after them but all in vain. Every swipe missed its target.
Eventually the little girl gave up and turned to her granny in exasperation.
"Granny!" she moaned.
"Those flies must have eyes in their arses because they can still see me when I sneak up on them from behind!"
A very logical deduction!
