What's The Rest Of This Rhyme? "My Face -- I Do Not Mind It Because I Am Behind It...." There's Another Line & Can't Remember It.

As a beauty, I am not a star.
There are others more handsome, by far.
But my face, I don't mind it,
For I am behind it,
It's the people in front whom I jar.

This is the whole limerick. There are, however, other versions with a few minor variations.
