Apologies if I've shared it before, but I was robbed by a squirrel gang once...
Outside the Admiralty museum in London, I stopped because a squirrel had scampered across the park, stopped in front of me and started pawing at the air, while standing on its back legs...
I crouched down to see what it was doing, and there was a sudden commotion in my pocket. Before I'd realised what was happening, the pair of squirrels had raced across the park and scampered up a tree with my bag of trail mix.
Cheeky little grey bastards.
There were a lot of squirrels scampering around that park, I'm pretty sure that I wouldn't have been the only person that was robbed in this fashion.
