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 blonde was trying to be friendly, so she smiled her biggest smile and said as sweetly as possible, "T-G-I-F" another time.
