A boy from Uni (Astronomy) once had the most charming nerd pickup line:
"Will you be my binary star ?"
But if you want hopeless, asking for a slap in the face kind of line... This one was from the jerk at the same Astronomy class.
"I can see .... (aye, THAT planet's name ;) ) well from here, care to come closer ?"
G.d the guy never tired of jokes about that cursed planet :rolleyes2
