Who doesn’t love Halloween?  Sure, dressing up is fun, scarfing down candy is great, but what’s really fun is using Halloween as an excuse to troll your friends or foes.  Pittsburgh Zoo staff have done a great job in th penguin exhibit for Halloween. Have a close look at this photo, by @Sammm: “Rest In Peace” pot shots were taken at constant Pens rivals the Flyers and the Capitals – right down to the San Jose Sharks, whom the Penguins handled nicely in last June’s Stanley Cup Final.
