So... I was watching Boys Over Flowers 꽃보다 남자 when I got to the scene when Jihoo tries to cheer Jandi up with ice cream... and I noticed something familiar when I looked at his hat... so I keep watching and when he stands up, I get a better view of the hat and it has horns, 2 eyes, and an X on it, just like the Tony Tony Chopper from One Piece!! Here's a screenshot I took: http://img13.imageshack.us/img13/8944/tonytony.png
If you look closely you can see the X.
