I made myself a snowball <br />As perfect as could be. <br />I thought I'd keep it as a pet <br />And let it sleep with me. <br />I made it some pajamas <br />And a pillow for its head. <br />Then last night it ran away, <br />But first it wet the bed.<br /><br />Sheldon Allan Silverstein<br /><br />http://www.poemhunter.com/poem/snowball/
