Okay this might be random but what if you went to karate and you were early to karate and went to a 711 down the street still in your karate uniform and when you get to the cash register some scrawny dude gives you a comforting smile and says "Are you a ninja?"
I feel like Modify from Lemon demon is the reason why Pilot Dib modified his arm into the bean launcher, or- attached that to his arm idk just a thought.
