City squirrels are hilarious, often trusting humans enough that they will take food from your hand. I have determined that the probability of a squirrel taking offered food items is directly proportional to the deliciousness of the food. This guy realized that a Tic Tac was not worth the chance that I would catch him and break his neck; after running the appropriate cost/benefit analyses, the squirrels that live in Moody's beer garden have determined that french fries are worth the risk.

Also, I once saw a squirrel carrying a dead mouse around in it's mouth. It was one of the most awesome/disturbing things I have ever seen.
