What crazy pickup line worked on you? (or for you?)

Her: is that Harry Potter you're reading?

She approached me on the bus when I was commuting. It was a couple of decades ago when HP was new and fun. She was fun too, but we only went on a couple of dates.

I'm not surprised at all. At the time, I was trying to be as social as possible. If she'd stomped on my toe and then asked me out, I'd probably have said yes.
