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.'""
