Thank Goodness Its Friday

Bryan got on an elevator in a building. When he entered the elevator, there was a young woman already inside and she greeted him by saying, "T-G-I-F". Bryan smiled at young woman 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 young woman 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 young woman finally decided to explain things, and this time she said, "T-G-I-F, Thank Goodness Its Friday, get it?" Bryan answered, "Sorry, Honey, Its Thursday."
