If you get asked common questions like the aforementioned, take it as an opportunity to respond with something unique.
I live down under in Melbourne, Australia and we've been getting some pretty nasty rain. Anyway, weather is always one of the openers girls would use to talk to me, so a good way to respond to "Pretty crap weather we're having to day, eh?" Would be: "You kidding? Its beautiful. Just like the rains down in Africa". That should get them interested... like "You've been to Africa" or something.
I'm sure somewhere in the "tips" part of this forum, there's another line about the tropical weather up in Cuba, but that's another patter (unless you've actually been to Cuba... or Africa.. or anywhere else that has interesting climate)
Then use your C+F routine, or bridge conversations with funny stories, etc. You know the routine... keep her interested, attracted, kiss-close,etc.etc.
Remember: There is no one method to getting a girl's number. Use what's comfortable to you, and make the best out of it
