Marvin B. Clever
Said, "Never say never"
Then won the war on war

The question to beg
About the chicken and egg
To be posed for evermore

Liar liar?
Pants on fire
It's true this is a lie

Above you will see
Examples of me
Or have they not caught your eye?

To conclude
A conclusion I elude
My goal is to mystify


What am I?
