A business man got on an elevator. When he entered, there was a blonde already inside who greeted him with a bright, "T.G.I.F." He smiled and relpied, "S.H.I.T." She looked puzzled and repeated, "T.G.I.F., more slowly. He again answered, "S.H.I.T." The blonde was trying to keep it friendly, so she smiled her biggest smile, and said as sweetly as possible, "T.G.I.F." The man smiled back to her and once again, "S.H.I.T." The exasperated blonde finally decided to explain. "T.G.I.F' means 'Thank Goodness It's Friday." Get it, duhhh?" The man answered, "S-H-I-T' means 'Sorry, Honey, It's Thursday!"
