Feeling dull, lost a brain
Or are you suddenly feeling insane
Don’t be afraid to call.
We have a couple of extra brains at your service.
One is smart and one is small
And there is one that knows it all
What is so special about my brain
You might ask?
Give it a test
Give it a task
The response in every case
Is very fast
My brain might not be very attractive looking
But it works very quick
And could help you get an ‘A’ in math
So, call me for a booking
