S* H* I* T*!

A business man got on an elevator. When he entered, there was another person 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."

Trying to keep it friendly, 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."

Exasperated, she 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."
