You look familiar

"You look familiar… did we have sex?"

Opener by Richard La Ruina. Most women will give you the OMG face, roll their eyes or walk away. A few with a cheeky sense of humor will laugh and play along, if you deliver it with a big smile so it's obviously a joke.

When to use it

Only in a playful nightlife setting, with a woman who has already smiled at you or is joking with her friends. Not during the day, not at work, never with someone who looks uncomfortable. A safer version that still plays with the same idea: "You look familiar… did we go to school together?"

Follow-up

If she laughs: "No? Shame. Then let's fix that and at least get to know each other first. I'm …" If she's put off, say "Sorry, bad joke" and leave her alone.

Why it works

It's so blunt that it's either funny or offensive, nothing in between. It filters hard: you'll only get a conversation with women who enjoy cheeky humor.
