The Sneeze - A Limerick Classic

Now the sneeze is a joy-vent, I s'pose
When you're tickled to death in your nose
A pleasing explosion
Creating erosion-
But you want to watch out where it goes.

The Brain - A Limerick Classic

To manage and keep up a brain
Is no easy job, it is plain
That's why a great many
Don't ever use any
Thus avoiding the care and the strain.
