A Perfect Picnic is a 2003 Sesame Street storybook. Ernie, Bert, Elmo and Zoe go to a park near a farm for a springtime picnic. The picnic is beset by an unrelenting series of disappointments. Bert is allergic to the flowers, a strong breeze blows Ernie's hat away, and a baseball lands in the chocolate cream pie. Ants, robins, chipmunks, cyclists and even a passing lamb do their best to spoil the friends' day. Finally, it begins to rain.
