Tai Shan, aka Butterstick, is 2 years old today. The National Zoo gave the furball a birthday treat made of apples, pears, and bamboo frozen in beet juice and water — and a giant number 2 that apparently scared him quite a bit when it fell over. It’s no beersicle, but it’ll do. Happy birthday from all of your pals at DCist, Tai Shan.
