I saw a Reddit post about someone's mom having a Funko Pop addiction and it gave my theory more weight...
Overheard: "When my bf and I move in together, he isn't allowed to decorate the place. He can have his own room and I won't have to see it." I was like...maybe he's a funko pop collector? "He's got all these heirlooms from his dead grandma." ...WAS HIS GRANDMA A FUNKO POP COLLECTOR?
