I don't like to use canned openers for either day or night game. Typically, I go semi-direct with whatever comes to my mind first. For instance, I'm walking to the post office and see a hot girl I walk up next to her and say "Want to go on a romantic date with me to the post office" while at the same time showing her my envelope. I'm at a grocery store and I see a hot girl with a full shopping cart I go up to her and say "looks good, what's for dinner tonight". I really show intent though with my body language and eye contact. The girls response will be based on how attractive she finds you and how your sub communication seems (confidence, determination, etc) rather than the exact words you say (as long as the words aren't extremely creepy or too "out there"). For night game I typically go right up to the girl, square up and just say "Hey, I'm Alex". Basically just assuming that she's been waiting to meet me. I find that one works the best. If she is sitting, I will pull up a chair and sit next to her and then say that. Sometimes, I fuck around with it and if a chick is by herself, looking bored I sit next to her and say "Hey babe, sorry I'm late". You get the picture

Your really hook by having strong body language and good eye contact much more then the exact things you say so I try to focus on that. A big DHV/Hook for me lately has been telling girls that I'm a sex coach, works quite well. Here is a more easy to replicate example. If a chick looks latina, I'll take a educated guess at what country she's from and more often than not I'm right. And if I am it will be a slight DHV. Then I'll ask her what cities she's from, she will say Medellin for example and I will be like "Ah a paisa" (local term for girl from Medellin). She will be like "how did you know that" and clearly intrigued that I understand her culture, then I will amplify it by nochalantly saying "Oh, I've traveled to Medellin a lot for work". That will spike her interest even more and she will ask me what I do. Then I will fuck with her and say "soy narco mi amor" (this means I'm a drug dealer my love) she will start laughing and I will have dhvd myself even more on humor, then she will ask me what I really do and I will say "I have a business that involves a lot of travel" (which further dhvs me) you get the picture....
