You can't just suddenly decide to be funny, especially if you know you dont have good skills to begin with. You obviously lack extreme confidence if you're on this site, so don't try to fake it. I have imense respect for a woman's ability to detect BS, and therefore try not to give them any. Confidence is built up, you can't just trick yourself into it.
I find that I am my funniest when im not trying. Relax, dating is a game, not a competition. Enjoy yourself and you'll come accross as relaxed, entertaining, and fun to be around. Just soak in the environment and point out some things you think are funny. Everyone has there own sense of humor, just dont force it to much or script it and you should be able to squeeze out a few chuckles.
If you go out there and pretend to be confident when your not, everything you say will come across forced. As for kino, search for threads about it. There are plenty of posts regarding how and when to initiate kino to get a good response.
