I think I'd apply for the position of guy who's super interested in something that's only interesting cause it's gsmeplay relevant. I'd stand by a river staring at it day and night and when the protagonist talks to me I'd say "I'd bet I could use a boat to cross this river."
I am going to be a youngster who's super enthusiastic about an article of clothing. My hat, my sparkly dress, my shorts, you name it. Then after my dialogue I do a spin and little stars shoot around my character sprite.
That's a good one. Really specific but also ubiquitous
