How about I not pay for my roommates laptop that I may have broken?
Why'd you break his laptop in the first place?
I don't know why, I was drunk.
It sounds like it was just an accident so I understand why you don't want to pay.  However, this should be a teachable moment for you:  you really should control your drinking.  Otherwise something similar might happen again.
You sure you should say that with a straight face?
You should make sure to take responsibility for your mistakes. While it may have been simply a mistake, it was still your mistake. It makes sense for your roommate to want you to make the situation right.
