Imagine a dimension where Rick is too young to have a Beth, meaning that Rick doesn't have somebody to go on adventures with (AKA no Morty). Now add yourself into the dimension, and soon you begin to wonder how you tie into the story. Well, imagine Rick breaking into your house, and trying to stay for as long as he possibly could. What could this young scientist possibly have up his sleeve? Now that's a question I can answer. Read the book ;)

cuz nobody else would

You just moved into a new neighborhood and started to notice that the people across the street were weird... extremely weird. This guy had an entire lab in his garage! You didn't know too much about much except science, as you dropped out of college to work on personal projects, but the guy across the street was beating you by a mile. You were so far behind that all you had so far was a modified car engine and a stun gun that malfunctioned a lot.

It was a lonely day at work working alone in the coffee shop on Easter Sunday. Nobody had entered the shop for the whole day... until a tall man with blue scruffy hair and a lab coat with a small child who is wearing a yellow shirt enter the shop.
