Keep a smile on your face.
Smile while you talk, while you listen, while you do just anything.
Smile is the most powerful weapon, it lets them know that you are a funny guy
to be around, and while you talk with a girl it can build comfort.
But dont overdo it because then it wont look natural, smile at approptiate moments.
GL.
Smiling can be over done though. If you look like the the comic book joker you're doing it wrong.
Think like one of those ambiguously gay dudes in Abercrombie & Fitch catalogues. They may be gay as hell, but girls look at them and think "OMG HOT!"
THe problem with forced smiles is that they are forced. If you feel like your muscles are straining while you try to maintaint a smile then it's going to look fake and scare people away.
Best advice is just think of things that genuinely make you laugh, even if no one else would get the joke. Smiling will be a natural byproduct and it will look sincere.
