Replying to I was drunk!

Okay I need some help. I was drinking lastnight with some friends. And my buddy brought some girl over and one of her friends. I didn't pay too much attention to them right away, because I was busy drinking. Anyway we all went to the bar, and I ended up dancing and talking to the one pretty much all night. Anyway the 4 of us ended up leaving everyone else at the bar, and headed back to my buddies place. (I was like right on) Anyway, get back there and things are going good... but then her friend decides to be a cock blocker, and says lets go home. Anyway she gave me her number and stuff, and told me to call her. I got her to type her number into my phone and stuff and she did. The reason I got her to do that though is because I was trying to get her to type her name in there too, because I had no clue what it was. FUCK! Anyway, I want to call her because she was hot, but I have no idea what to say when I call. How can I find out her name? None of my buddies know what it is either. Let me know what I should do.
