TGIF

Another form my usual, but I think he has a new source...

A business man got on an elevator. 

When he entered, there was a blonde already inside who greeted him 
with a bright, 'T-G-I-F.' 

He smiled at her and replied, 'S-H-I-T.' 

She looked puzzled and repeated, 'T-G-I-F,' more slowly. 

He again answered, 'S-H-I-T.' 

The blonde was trying to keep it friendly, so she smiled her biggest 
smile, and said as sweetly as possibly, 'T-G-I-F.' 

The man smiled back to her and once again...'S-H-I-T.' 

The exasperated blonde finally decided to explain. 

'T-G-I-F' means 'Thank Goodness It's Friday.' Get it, duuhhh?' 

The man answered, ''S-H-I-T' means 'Sorry, Honey, It's Thursday'
