Animals just can't get enough of delicious human food.

Take this brazen squirrel who jumps into a New York City garbage can and swipes a milkshake that still had some milkshake in it (we know, we know -- who in their right mind would throw out an unfinished milkshake?).

Like the famed pizza rat that took the Big Apple by storm, this squirrel is pretty determined and has that gusto you need to make it in New York.

Look at him scamper around, which is good. He's going to need to burn some calories after wolfing down all those calories.

It just goes to prove that one man's trash is actually one squirrel's treasure.
