AnimalsJokes A City Kid Went To His Grandpa's Farm. This Is Super Funny. 9.8k Views A city kid went to his grandpa’s farm for the weekend. He tagged along as Pa did what had to be done around the place, taking it all in. Then Grandpa came across a cow having trouble calving. He didn’t know how the whole process would be taken in by the six-year-old but had no option but to get on with the job of assisting the birth. When the calf had been ‘pulled’ and the cow was happily cleaning it up, Pa asked the boy if he had any questions about what he had just seen. At first, the kid seemed overwhelmed by the experience, but finally asked, “Just how fast was that calf going when it hit the cow’s behind?” See more Previous joke An Elephant And A Mouse Are Walking.
