One day, a baby camel and its father had a conversation.
Baby Camel: Dad, why do we have humps on our backs?
Father Camel: Well, son, our humps contain the fat necessary to sustain us though all the days when we’re out in the desert.
Baby Camel: Oh, okay. Dad, why do we have long eyelashes?
Father Camel: They’re to protect our eyes from the sandstorms which rage in the desert.
Baby Camel: I get it now. Dad, why do we have big padded feet?
Father Camel: Because the sand in the desert is very soft and we need big feet so that we can walk on the sand without sinking.
Baby Camel: Thanks, Dad. So what are we doing in London Zoo?
