A couple and their little 5-year old went to a pet shop to teach the little kid responsibility for caring for a pet. They decided on a little turtle because it would be easy to take care of.
The family returned the next day and showed the pet shop owner that the turtle had blisters on its stomach and shell. They exchanged the turtle and left.
The family returned again the next day, same problem. The pet shop owner was obviously concerned, so he exchanged the turtle and was talking to the parents about the proper care of turtles when they looked over at the child gripping the turtle by the sides and running the turtle on the ground and going "VROOM! VROOM!".
