Monkey talks, monkey listens. Persons who think alike will understand one another.

Five little monkeys sitting in a tree,
Teasing Mr. Crocodile: “You can’t catch me!”
Along comes Mr. Crocodile
As quiet as can be and…SNAP!

Four little monkeys sitting in a tree…
Three little monkeys sitting in a tree…
Two little monkeys sitting in a tree…

One little monkey sitting in a tree,
Teasing Mr. Crocodile: “You can’t catch me!”
Along comes Mr. Crocodile
As quiet as can be and….SNAP!
And away swims Mr. Crocodile as full as he can be!

Ukila na timsaha, hutapata nyingi raha.   
If you want to eat with the crocodile, you will not have much pleasure 
Do not be too ambitious; stay with your own people.
Timsaha [dialect], mamba, ngwena:  crocodile.
