Welcome to Using English.
I remember this scene, but I don't believe you have transcribed it correctly. "mad daddy" in particular doesn't sound right.
However, the overall meaning is that Penny is a cute girl, and you are a nerd. Compared to the rest of the world, you probably would not be able to date her, but compared to the other people in this car, who are way nerdier and weirder than you, you are the person most likely to get to date her.
Please remember that capital letters are an important part of correct English.
