A gray hippo lived in the zoo br It was so stressful it turned him blue br The giraffes laughed at his skin so blue br That only made him bluer times two br Now the lion was wise but a little slow br That's how he wound up the star of the show br He and hippo played a game called solitaire br While the lion played fleas were biting him everywhere br Hippo ate chocolate cake that the tourist br Threw over the gate br Wise old lion said, 'You better watch your weight. br You're getting a little thick in the hip '.
