I don't know if anyone else noticed this but in this episode Paddie is talking to himself in the mirror on Baratie and in the bottom left corner of the mirror is the word "Eichiiro". I just found this interesting.
(japanese version) ep. 20 observation
That's cool, I like when they hide secret things especially in the manga too.
There're alot of those type of Easter eggs in One Piece. I could've sworn I saw "Toei" written on a book or a wine bottle once. Let's not forget about Pandaman, too.
It reminds me of the 'hidden' or 'inside meanings' you find in the 80's transformers where they had the word 'BEER' in the back ground.
In the movie with the baseball extra on the score board you see some sort of password/cheat code.
You never notice things till you REALLY look sometimes.
