Photography blog Spicuzza Photo A Day has documented a fun moment from the San Francisco Zoo. A little boy accidentally dropped his Nintendo DSi XL game system into the Gorilla habitat, drawing considerable interest from the residents who did their best to figure the device out. You have to love how quickly the gorilla seemed to work out how to hold it correctly and even at one point raise it up to its eye like a camera. The exchange didn't last too long, a trainer soon showed up with a shiny red apple, using it to work out an exchange for the device and return it to its owner. View more photos of the incident here.
