Another Blonde Joke

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 at her & replied, "S-H-I-T!" She looked puzzled, & repeated, "No,T-G-I-F," more slowly. He again answered, "Noooo, S-H-I-T."  The blonde was trying to keep it friendly, so, she smiled her biggest smile & said as sweetly as possibly, "Ok, well, T-G-I-F." The man smiled back to her, "Like I said, S-H-I-T." The exasperated blonde finally decided to explain, "’T-G-I-F’ means ‘Thank Goodness It’s Friday.’ Get it duuhhh?" The man answered, "Yeah I know, and `S-H-I-T’ means Sorry, Honey, It’s Thursday".
