Japanese deer don't play coy when they want some food.

Is it bad that I make a similar sound when I'm hungry? (via YouTube)

Gavin Shapiro and his friends were visiting Japan when they ran into this cute lil' dear squeaking its little lungs out. They approached to investigate, but when they got closer, the deer belted out what can only be described as a demon-like war cry. The reason why? According to Outdoor Hub:

Sika deer in the city of Nara, Japan have a reputation for being friendly—if a little pushy—and are a popular tourist attraction due to their habit of “bowing” for food. It is a behavior that they seemed to have picked up from humans and it's likely that if you approach one of these roving herds with food, they'll “politely” hound you down until your hands are empty.
