In college we had a squirrel that lived right outside of our apartment, which was smart on his part since it wasn't uncommon for late night food to be dropped, left, or forgotten before getting inside. One time he came into our apartment and dragged a piece of old pizza outside for a snack, which was an incredible site and reminded me to keep my digital camera charged in case it happened again.

We never saw him steal another slice of pizza, but we did witness him carry an entire Jimmy John's sandwich up a tree, finishing the ENTIRE thing. Truly amazing.
