"The Lord is My Shepherd" joke

The Lord is my Shepherd, I shall not flunk;
He keepeth me from lying down when I should be studying.
He leadeth me beside the water cooler for a study break;
He restoreth my faith in study guides.
He leads me to better study habits
For my grades sake.
Yea, though I walk through the valley of borderline grades,
I will not have a nervous breakdown;
For thou art with me.
My prayers and my friends, they comfort me.
Thou givest me answers in moments of blankness;
Thou anointest my head with understanding.
My test paper runneth over with questions I recognize.
Surely passing grades and flying colors shall follow me
All the days of my examinations,
And I shall not have to dwell in this university forever,
Amen!
