When I was but a young lad, I had a juvenile barbary macaque climb up on my shoulders because it was inquisitive about a plush macaque toy that I was holding (this was at gibraltar, they sell the toys in the gift shops). Anyways, he soon became disinterested in the toy and proceeded to see if I had any tasty bugs on my head. Things were ok (I was a little bit freaked out) until the mother found out that one of her babies was missing and became pretty upset I had, to the best of her knowledge, kidnapped her baby. To make a long story short, I almost lost a finger.
