A business man got on an elevator in a tall building. When he entered the elevator, there was a blonde already inside and she greeted him by saying, "T-G-I-F." He smiled at her and replied, "S-H-I-T."

She looked at him, puzzled, and said, "T-G-I-F" again. He acknowledged her remark again by answering, "S-H-I-T." The blonde was trying to be friendly, so she smiled her biggest smile and said as sweetly as possibly, "T-G-I-F" another time.

The man smiled back to her and once again answers "S-H-I-T." The blonde finally decided to explain things, and this time she said, "T-G-I-F. It means Thank Goodness It's Friday. Get it? duuhhh!"

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