Butterstick Takes It Up The Hindquarters For Science

The life of Butterstick the National Zoo panda follows an all-too-common trajectory: we've seen him grow from adorable infant to teenage crack-whore to compulsive leg-humper and now, to a middle-aged adult with irritable bowels.

Butterstick had to get a colonoscopy as part of his yearly checkup. Apparently he developed an "inflammatory bowel condition" last summer and lost 30 pounds, so vets wanted to make sure his colon was OK.

Oh but fear not, America! The exploration revealed a thrivingly healthy colon, plus two gerbil skeletons and the ghost of Rod Stewart.
