I have a brain
It is not in vain
It is not a stain
It'll produce grain
With might and main
From a drop of rain
With a mind serene
An edifice or a train
Or any other gain
If you've been sane
Not for a moment insane
Never with it to part
To produce every art
From the heart of your heart
Thus, you'll be smart
And eat the delicious tart
ساحة النقاش
