We need to talk about monkeys

Anybody else notice how the word monkey is often used to refer to apes as well as monkeys? Is nobody else aware that monkeys and apes are not the same animal? I don't understand why this mistake is so prevalent when the differences between monkeys are quite clear. The easiest way to tell the difference is that apes do not have tails. Always remember before you call an ape a monkey you gotta check that ass. If you don't see a tail that is not a monkey!
