Octuplet Down

To what effect
Do you think?
Better to check
Than to shrink
Too late to try
You'd rather deny
Time to behead
Your professor, he's better off dead

Octave down, oh, octave down

Much to decide
When you're young
Thought twenty five
Meant you were done
Who told you their philosophy?
Don't change your mind
Teachers' bankrupt from her head to her feet
