A priest goes to get his hair cut. When the barber's done, the priest goes to pay him, but the barber says, "No thanks, my friend. I couldn't take money from a man of the cloth." The next day the barber shows up for work and there's a dozen boxes of chocolates waiting for him with a thank you note from the priest.
That afternoon a rabbi comes in and the barber cuts his hair. When he gets done the rabbi goes to pay him, but the barber says, "No thanks, my friend, I couldn't take money from a man of the cloth."
The next day when he shows up for work, there's a dozen rabbis waiting for him.
My wife was angry. She said: "It's unfair! A guy can screw a different girl every week and he's considered a stud. But if a girl screws even two guys in a year she's called a slut."
So I man-splained it to her: "Think of it this way. If a key opens lots of locks it's a master key. But if a lock is opened by lots of keys... well... it's a shitty lock."
