A business man got on an elevator in a 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 blond 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 replied with a quizzical expression, „S-H-I-T“.

The blond finally decided to explain things, and this time she said, „T-G-I-F, Thank goodness Its Friday; get it?“ The man answered, „Sorry, Honey, It’s Thursday“.
