A blonde inside greets him with a smile and says, "T.G.I.F!"The businessman returns the smile and responds, "S-H-I-T."The blonde, puzzled, smiles her biggest smile and repeats as sweetly as possible, "T.G.I.F!!"The businessman shoots back with a quizzical expression, "S-H-I-T."The blonde, frustrated, decided to explain things. "T.G.I.F" Thank Goodness It's Friday-get it?"The man grins. "Sorry, Honey; It's Thursday."
