Very good stuff!
The only thing I've gotta wonder about is making fun of her degree... yeah, you're right, it's a phony degree. But it seems like you're just putting her down rather than making her laugh at herself... that one's a bit too heavy on the ****y and light on the funny I think.
Other than that, they're great. And I think you've hit on the point I've begun to realize, too... tongue-in-cheek presumptiveness is a great way to go. With this girl I've been seeing, I've stopped asking her to do things, and started mentioning things I want to do as if she's already agreed to them. I don't ask, "do you want to come over and watch this movie with me?" I say, "So when you come over to watch this movie we're gonna have to finish (blah blah blah whatever)..." If I have to ask a question, I don't ask, "Do you want to..." Instead it's "When do you want to..." or some other thing that assumes she's said yes and seeks more details.
I've also started speaking matter-of-factly about my great power and wealth... with outrageous details so I'm obviously joking but in a serious, confident tone. It's a great way to be playful and seem powerful and ambitious without seeming dishonest or arrogant. For example, saying, "I'm buying Australia next week," in a casual, routine tone, as if you've just told her you're buying a new toothbrush, can be a great start to a really funny conversation... you can convey power and ambition without looking like you're bragging, all while making her laugh. And of course she knows it's just make-believe... but I'm not sure her feelings know the difference.
I haven't field tested these ideas extensively but they seem to make a lot of sense and they're working well so far.
