Wikipedia tells us that "an ape is any member of the biological superfamily Hominoidea" which includes chimpanzees, gorillas, orangutans, gibbons... but not monkeys. Which is annoying. The reason why it's annoying is that we came up with an ape-based picture quiz involving all these animals - and monkeys - to celebrate the cheeky, um, monkey that's appearing in the Hangover II this month and Project Nim a few months from now. Hmm. So if you're willing to overlook our biological classification blunder, here is the quiz, and we hope you like it. Oook ook oook.
Looking for a hint? The forum has the answers... well, some clues, anyway.
