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 “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.
