What pickup lines do you use to start a conversation with someone you are attracted to?
I walk up to a girl and say 'Giant polar bear', she responses 'Huh', or 'What', then I go 'It broke the ice'. This one never failed me. I always get a smile back. Even when I come across with someone who answers with 'It broke the ice', I throw another one until I come up with something she doesn't know. This line always follows with a counter question about the success rate.
How do they typically respond?
As I said, somehow this line always works. It is witty. As the conversation goes a bit further, just as I am introducing myself, I say (very cheesy) "Name is Bruce, but you can call me tonight". This gets a puzzled response at first and a smirk -if they don't know it already-, but if they do, I squint my eyes with a big smile :)
