"I like your smile, it's a good smile"
--let her smile for you--
"Ever heard of C's and U's?"
--Run the C's and U's routine--
"They used to judge the best race horses by their smile"
--look for the "my friend used to laugh like a horse back in grade school, he also used to run around when he gets excited, braying and whinnying like a horse" routine. The neg-hit of the routine, or compliment "Your smile reminds me of him, he was a cool guy, he's probably like in college right now, he was a geius" OR "your smile reminds me of him, he was a funny guy, you and me should chill sometime, you seem cool like that"--
Once you get her interest up, ask if she's going to stay for a bit. Go off and run your track A game, then get back to her, ask for her number, if she knows anywhere that's going to be fun later in the week, ask for her number, and say you'll meet her there.
