Here's a line a friend of mine and I came up with when I was around the age of 21.It requires a few physical ques as well.
First, go down on one knee and grab the future Miss. Nerdlimgs hand. Next the pick up line." Fair Lady I am here to offer you an artifact known as the Rod of temptation. Should you except a boy will become a man this day.( wipes tear from eye) Do you except?"
Sad thing is my friend tried this on random girl at a casino and it worked. He left us behind and that was the last we saw of him for a few days.
