Outsmarted by a bunny

When cousin A brought his new pet bunny to play with the twins, the bunny didn't think that being held in the clutches of these two boys would be a good idea and so it tried to run away, which led Peter and Patrick to chase the bunny. After running around a bit, the bunny would always head under the piano. And under the piano would Peter and Patrick go, but the twins are just a tad taller than the piano now and every time they would try to stand up, they would bump their head on the piano,  which led to the boys crying, and a free bunny.
