The other day, I was getting into an elevator. As I entered, a blonde woman already inside greeted me by saying,
 
"T - G - I - F."

I smiled at her and replied, "S - H - I - T."
 
She looked at me, puzzled, and said again, "T - G - I- F."
 
I acknowledged her remark once more by answering, "S - H - I - T."
 
The blonde was trying to be friendly, so she smiled her biggest smile and said to me as sweetly as possibly, "T - G - I - F" one more time.
 
Then I smiled back at her and once again replied with a quizzical statement, "S - H - I - T."
 
The blonde, finally deciding to explain, said, "T - G - I - F, Thank Goodness It's Friday.....get it?"
 
I answered back, "S - H - I - T....... Sorry, Honey, It's Thursday."
