A woman hails a cab in NYC， jumps in and says to the cabbie. “T.G.I.F.”
The cabbie just shrugs his shoulders and says， “Huh？”
She repeats， “T.G.I.F.”
The cabbie thinks about that for a moment and says， “S.H.I.T.”
Not understanding， she inquires about the meaning of the acronym.
The cabbie responds， “Sorry Honey， It's Thursday！”
