Li'l Johnny was accompanying his Grandma to the departmental store.
On the way, he finds 2 dogs having sex.

Johnny prods his Grandma and asks what the dogs are doing. Grandma
gets too embarrassed, after a thought says, "Johnny, the dog that is
on the top has hurt its paw. So the other dog is taking it to a
vet."

Johnny replies, "My what is happening to this world... you give a helping
hand and they fuck you all the way."
