What is your most embarrassing wardrobe malfunction?

I was at a Friday Happy Hour with a social group that I was a member of. While I was talking to a girl I had just met the previous Friday and one of her friends, my zipper popped. Without hesitation, I pulled out my tucked shirt and let it fall over the broken zipper. The two ladies had no idea what I was doing. I started dating one of them shortly after that and only then did I tell her what I had done. She laughed and said they wondered why I had un-tucked my shirt. We have been married now for 31 years and I still tell her that I was so excited when I first met her that I popped my zipper when I saw her.
