The wise man and the foolish man

This one I remember from primary school, and I can even recall the actions too :)

The wise man built his house upon the rocks
The wise man built his house upon the rocks
the wise man built his house upon the rocks
And the rain came tumbling down.
Oh the rain came down and the floods came up.
The rain came down and the floods came up.
The rain came down and the floods came up
And the house on the rock stood FIRM.

The foolish man built his house upon the sand
The foolish man built his house upon the sand
The foolish man built his house upon the sand
And the rain came tumbling down.
Oh the rain came down and the floods came up.
The rain came down and the floods came up.
The rain came down and the floods came up
And the house on the sand fell FLAT.
