Using a random word generator, try to quickly make a relevant monologue to your friends on the word that generates. Your friends will judge you on your performance. The object of the game is to be spontaneous. For bonus points, generate two words and connect them somehow.

Example: I had two SAT-type words about cleaning clothes and being frugal. (I don't even remember what the words were, because I had never heard of them before.) I talked about how people spent hundreds of dollars each week on cleaning the same work clothes at the dry cleaners. They could be using that money to fund retirement or making a down payment. Instead it goes to feeding this corporate culture we're all expected to adapt to.

The benefit is that you learn how to develop strong impromptu conversation skills. There's so many different kind of girls, so you don't know what kind of topics you might encounter that are important to them. I talk about things that are significant to me, because it comes out naturally.

Play to your strengths and work to eradicate your weaknesses.
