Retrograde

From one woman on the bus to another one... complete strangers:

Woman #1: "Mercury goes into retrograde tomorrow."

Woman #2: "Oh yeah? What's that?"

Woman #1: "It means that in astrology Mercury will look like it's going backwards. And Mercury is the planet in charge of the post office, so we can expect a lot of foul ups."
