Butter wouldn't melt... right?

I'm at London Zoo for my first late night session of the season.

I only took my 50mm lens because it was mainly a social visit but managed to get up close to this Squirrel Monkey.

Looks cute, but the keeper told me, they'll jump on you, or fight.

Alternatively one might sit on a branch and pee on your head or even pinch your drink. My friend Susana was asked to hide her orange juice as although they can't manage the screw top they've got sharp teeth.
