Yes, this may be a dumb thread but this is a forum after all. XD
Judging from personality(among other things) which OP characters do you think wear boxers, briefs, or neather heh. If you only knew what sparked me to make this thread. XD
I say Sanji wears briefs if for his kicking alone, and with how much Sanji loves girls and are turned on by them its a good thing if he did cause briefs are tight if you know what I'm getting at. XD
