LMFAO at above post...personally I found the "Hello, my name is ____, I noticed you and thought that i just had to introduce myself and maybe get your name in return and maybe even ask how your days has been so far..." work more than any cheesy line you'll "learn" from buddies. From there, it's up to you to keep that conversation going and interesting.
Intelligence, tact, grace and sense of humor will get you further than some "pick up line" ever will. 8+ ladies hear the same lame shit from random douche bags all day..stand out some, be creative in your conversation. What ever you do don't mention her looks...
