Worst pick-up lines you've seen/heard/used

...because every forum needs one of these topics?

Nah, I'm lonely, my love life is rather inexistent, so I decided I need to laugh at the whole dating thing a little bit. Even if you just hit me with the classics, it'll be worth the groan and giggle.

I remember having hosted, long time ago, a contest about the worse pick-up lines and the appropriate answers for them. Here are some I remember:

- Can I have a picture of you, so I can show Santa what I want for Christmas?
- I'm sorry, I'm allergic to reindeers.

- Hey doll, do you come here often?
- I used to, but it won't happen again.

- Is the chair by you free?
- Yes, and if you sit on it, this one under me will be free too.
