A purple hippopotamus went to the store one day. "Hello." Said the purple hippopotamus. The people stared. He walked into the grocery section. "Hello." Said the purple hippopotamus. The people stared. He perused the cereal isle. "Hello." Said the purple hippopotamus. "Why aren't you wearing any pants?" The little girl asked. "Oh." The purple hippopotamus looked down at his pantless bottom. "Oops." He selected a box of lucky charms, then walked to the checkout line.
