This is funny and it´s not really my idea, i got it from a youtube comment.
Here is what he says
"Eh, here's how I see it...
Luffy: Jinbe, be my nakama!
Jinbe: I must refuse, Luffy-kun. Fishman Island needs me--I can't go with you.
Luffy: ...*destroys Fishman Island* Now you can!
Suddenly, Shirley's prediction makes sense."
