Every time I hear the word Gemini, I think of an argument I was having with my ex. I forget why we were fighting, but it may have been about another woman. She said to me, "I always knew you were a Gemini." (This struck me as odd, since we are both Virgoes, with our birthdays being a couple days apart, but I figured I'd play along.) I asked if it was because I am like my buddy, Erik, and she said yes. (Erik is a Gemini, and is somewhat of a ladies' man.) I replied, "I thought that is what you meant, because you are not bright enough to use the word 'Gemini' to make a 'two-faced' insult."
That was one of the best pwnages I ever got on her...
