In SBS volume 73:
D: Hey, Oda! In all of these fight scenes, why doesn't anybody go for the men's groins? Doesn't that seem like the quickest path to victory? P.N. Eldest of the Asada Siblings.
O: True, that is a vital area. Just imagine legends among men--Whitebeard, Shanks, Mihawk--staring each other down, bearing their weighty ideals...and trying to whack each other in the balls! IS THAT THE KIND OF MANGA YOU WANT TO READ?!
He includes Mihawk in the same context with shanks and whitebeard, it may just be because they are all big names in one piece world and to fans, but its fun to think he just thought of the 3 strongest people to come to mind.
