Nothing too weird.... but that's not good. I need to get out of my comfort zone more.
1 comes to mind is when I was sitting next to a girl at a traffic light, both of us in our cars. I honked like a bunch of times until she finally looked over. She rolled down her window, and I told her she was beautiful, and then she said she had a boyfriend. Not weird, but interesting experience.
The other approaches that I consider "weird" are where I've asked a girl out during the day... absolutely beautiful women... and they had a huge expression of shock and elation and were like "no one has ever done this to me!" Even though they were some of the most attractive girls around.
I need to do more interesting approaches and get some better weird stories :\
