How miserable do i have to be before you’re happy?

Lisa? Ugh! Not her again
Yeah, Lisa, can't you leave me alone? We're over
You're not over, you never were! Milhouse, you're a great guy, but we're not gonna work out for one reason
It's because you'll always be in love with her

You don't want me to be with you, you don't want me to be with someone else
How miserable do I have to be before you're happy?

Lisa, does this mean you like me?
Yes. No! I don't know! It means that that life is full of unexpected things and you should never give up
