You're in a club/bar/other location. You've spotted someone who has taken your fancy. Glances have been exchanged and their body language is an invitation to approach. You walk towards them, trying to come up with a good opening line, and then...

Do you have a tried and tested chat-up line?
Have you ever used, or had a really corny line used on you? Did it work?
