Okay, I was just talking to 1 2 Jango and I came up with a crack theory. Yes, it was as a joke and I know this thread will get locked but dammit, I wanna post it! XD
Okay, as we all know "X Marks the spot" Correct? Well, Choppers hat has a big X on it, thats right, Choppers hat.
Choppers hat is One Piece! Why else would someone give a reindeer a hat?
And as Jango said: "it just sounds silly. watch, it'll end up being true lol"
Everything is possible in the One Piece world. XD
