Broccoli Theology poem

Want to be a greengrocer?
Study broccoli theology
Learn rhubarb pathology
And get some fancy letters after your name
Want to be a window cleaner?
Take a climb up a ladder course
Take a climb down a ladder course
And get some fancy letters after your name
Want to be a poet who doesn’t know it?
You can’t just do it, read through it
Copy dead people who knew it
And get some fancy letters after your name
Want to be a qualifications provider?
Study ABCDEFGHIJKLMNOP
QRSTUVW, X and Y and Z
And get some fancy letters after your name
