James MacDonald got it started over at Making Light:
You got problems with your writingBut I must say my favorite comes from Stephen Frug in the comments:
She said to me
The answer’s easy if you
Put your B in C
I’ll show you how to move along
When you find you’re up a tree
There must be fifty ways
To plot your novel.
A man throws down his pencilShare and enjoy!
He says why am I stuck in the middle now
Why am I stuck in the middle
The rest of this book is so hard
I need a writer's resort vacation
I want a shot at a Nebula
Don't want to end up a remainder
On a remainder table ...
