Well, little Johnny’s class was on a field trip to the local park. While they were walking along, Miss Pritchett, the substitute teacher was pointing out the various shrubs and trees. Unexpectedly they came across two dogs who were in the act of fucking. Little Susie, who was a bit naive asked Miss Pritchett what was going on. Miss Pritchett, in an attempt to diffuse the situation, said “Oh, the dog in back has two bad front legs so the dog in front is helping the one in back to walk. Isn’t that nice.” Little Johnny surveyed the scene for a bit and then added “Isn’t it the truth. You try to help out someone and you end up getting fucked in the ass.”
