Do I know you from somewhere?...What are the best lines someone has said to you?

I think the funniest one and the only one that actually got me to talk to the guy was "Didn't we go to different schools together?" It took me a moment to realize what he had said and then I started laughing. I let him buy me a drink and we started talking. The funniest part, we actually went to the same high school, he was 2 years ahead of me so he honestly had never met me. We really laughed about that one! We dated for about a year and then decided we just really weren't feeling it for each other as more than friends. We are still friends 15 years later and I absolutely adore his wife!!
