Rick: I should get her pregnant, then she'll have to marry me.
Jerry: I beg your pardon, Rick, INAPPROPRIATE.
Rick: Sorry, please proceed with your story about banging my daughter in high school.  I'm not sure you want to take romantic advice from this guy, Morty, his marriage is hanging from a thread.
Jerry: My marriage is fine, thank you.
Rick: Jerry, it's your house, whatever you say it is is how it is,  but I think a blind man could see that Beth is looking for the door. I barely have a reason to care and even I noticed.
Morty: Come on, Rick, don't talk about my parents like that.
Rick: Listen, Morty, I hate to break it to you, but what people call "love" is a chemical reaction that compels animals to breed. It hits hard, Morty, then it slowly fades, leaving you stranded in a failing marriage. I did it, your parents are gonna do it. Break the cycle, Morty. Rise above. Focus on science.
