Seriously. Squirrels give me the wilies, ever since one of them got stuck in my basement kitchen and couldn't get back out again. It was like those bike races you see when the bikes are going sideways around the track -- it whizzed around the friggin' walls. And it screamed. Guess what? So did I. I left my back door open (all at the other end of the apartment, the only door out) and left the place for hours. I still came back in with a broom (like that would have protected me because that little mofo was pissed).
So trying to throw out my empty Starbucks cup at the beaches in Toronto became a terrifying experience based on the following video. EEEEEEEK!!!!
