This probably only works if you're Richard Feynman.
I always wondered how he did it so I asked him and he told me his pickup line.
He said:
"I go up to a girl and I start off with saying hi, introducing myself as Ed, I then say to them this line"
"Look, girls are into honesty right? Well the truth is I have a big d!&k and want to put it in you"
He told me that the secret to it is that you have to sell it like it was the most normal thing to say in the world.
As you can imagine, I was completely stunned, but he swore it was the truth.
It's a little more crude than feynman's article, but the principle is similar.
Strange huh?
