A pickup line which I would be very careful about using:
You: Want me to teach you how to make a 10 hour omelette?
Her: What's a 10 hour omelette?
You: Well, you take ten minutes to get everything together that you need... eggs, a skillet, some cheese, a bit of butter, some bacon, some ham, and maybe a few mushrooms. Then, you put it into the refrigerator, we go fuck for nine hours and forty-five minutes, and then come back and make two omelettes for breakfast.
YMMV on this one!
