Two of Me

I was at a gathering and somehow I was there twice.  There were two of me identical in every way.  It was decided that one of the two me's should be killed to avoid confusion.  I kept telling everyone I was the real me but nobody was convinced.  An old girlfriend said she had placed an X on me in case something like this happened.  I looked down at my knee and there was the remnants of an X on it but it was mostly worn off.  Nobody was convinced I was the real me.  There was a line of people waiting to get in to a house.  some of them were reading a comic book about skeletons.  I told them I had the original and that the one they were reading was a reprint.  I told them the original was in black and white and the one they were reading was in full color.  My old girlfriend then said I was the real me because the other me could not possibly know that.
