I don't have a bad one, but back in 2009 when Pedro Martinez was working his way up to the Phillies, he stopped and played for the ironpigs. He had a bullpen session, and after, he walked over to the rail and I was the first to get his signature. As he was signing my card, I figured I'd ask him for his headband. He looked up and said "Do you want my DNA?" And I was like uhh and he just laughed and gave it to me. Attached is an article with his picture from the bullpen session. You can see he has a grey headband on, that I now own
