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 (letters only).
He smiled at her and replied, S-H-I-T (letters only).
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 It’s Friday, get it?
The man answered, Sorry, Honey, It’s Thursday.
