 A little boy walking with his father sees two dogs mating and asks his father what they’re doing.

Not wanting to compromise his son’s innocence, the father says,

“Well, son, one of the dogs is hurt and his friend is helping him home by carrying him on its back.”

The little boy replies,

“Gee, Dad, that’s just like life. Try to help out a friend and they’ll shove it up your ass every time.”
