A businessman 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 at her and replied, “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 at her and once again, “S-H-I-T.”
The exasperated blonde finally decided to explain. “‘T-G-I-F’ means ‘Thank God, It’s Friday!’ Get it, duuhhh?” The man answered, “S-H-I-T means ‘Sorry, Honey, It’s Thursday’—duuhhh.”
