As you may know, there are 2 kinds of monkeys: "Old World" (Africa and Asia) and "New World" (Central & South America).
Scientists think that monkeys originated in the Old World, and then rode rafts to the New World.
All the other monkeys laughed
when I said: Look at my raft!
I ignored them, and, what a thrill,
I'm cruising to Brazil!
Okay, that's not the theory. The theory is that they were sitting on big coastal masses of vegetation, on the shores of the Paleo-Atlantic. Then the vegetation broke away.
The voyage occurred by error,
and they floated away in terror.
But the Atlantic wasn't so wide
and they reached the other side.
