A nun and a man were standing in an elevator. Being the nice person 
that she was, she looked over at him, smiled, and said: "T. G. I. F." 

The man looked back at her and said "S. H. I. T." The nun was shocked. 
She turned to the man and said: "There was no reason to be rude, all 
I said was Thank God It's Friday. "

The man looked back at her and said: "Well you must have misunderstood 
me because all I said was, Sorry Honey It's Thursday"
