An old Fitter sat down at the bar and ordered a drink. As he sat Sipping his drink, a young woman sat down next to him.
She turned to the Fitter and asked, "Are you a real Fitter?"
He replied, "Well, I've spent my whole life, breaking flanges, Grinding valves, repairing leaks, scraping bearings, investigating problems, Re-building pumps and overhauling compressors, so I guess I am a Fitter."
She said, "I'm a lesbian. I spend my whole day thinking about women. As soon as I get up in the morning, I think about women. When I shower, I think about women. When I watch TV, I think about women. I even think about women when I eat. It seems that everything makes me think of women."
The two sat sipping in silence.
A little while later, a man sat down on the other side of the old Fitter and asked, "Are you a real Fitter?"
He replied, "I always thought I was, but I just found out I'm a lesbian."
