JokesMarriage A Boy Was Once Given The Task Of Babysitting. This Will Blow Your Mind. A boy was once given the task of babysitting his teacher’s pet dog for a day. He was careless and the dog ran out the door when he wasn’t looking. He tried searching all over town but he couldn’t find the dog anywhere. He then thought of a plan. His teacher was old and losing the sharpness of most of her senses. She probably wouldn’t notice the difference if he bought a new dog and pretended nothing had happened. But when his teacher returned home and saw the new dog, she immediately called the boy and scolded him for not only losing her dog but also trying to cover up his mistake. It just goes to show. You can’t trick an old teacher with a new dog. See more Previous joke A College Student Was Golfing With An Old Man. Next joke A Couple Is Taking A Tour Through The Natural History Museum.
