"I'm no scientist but I know science when I see it."
"I may be Bill Nye because I have my ion you."
"Do you mind if I follow you home? My mom said to follow my dreams."
..... The list goes on and on. 13-year old has been collecting clean pick-up lines. He writes one a day and gives it to a girl friend (he is sure to clarify not girlfriend) at school - often she writes one back.
Yesterday he was quite humored when he came home from school. They were learning about sine, cosine and tangent of x in math that day. He passed a note to his friend, "You must be x because I want to know your sine."
