Grretta had packed Grrr a fine lunch of dinoburgers and root-beer.  Bob had agreed to fill in for Grrr at the "Wellness Center". Grrr had one foot out the door when he heard Grrr, Jr.  throw his history book at the wall. Walking back into the cave, Grrr went to his son's room and asked,

"Why are you hurting that  beloved history book?"

Grrr, Jr.  looked up at his father in despair, "I am going to fail on Monday, I will be off the team and not able to take Rexy to the Prom...I study and study dad, you know I do. But

I just don't  get it...The Reformation.. Luther..Calvin..Cromwell..I just don't get it".

"Hold on son."
