Clown sex
Who doesn't want Buggy to honk their horn?
Shanks: "Do you know how hard it is, to see that beautiful red nose shining in the sun all day long, and not go up and give it a squeeze? These are the moments of peace that make all the fighting worthwhile. Give me all of your big, red nose, Buggy."
Buggy: "B-B-Baka, you better not be lying about that treasure map! That's the only reason I'm doing this, Shanks! I-It's not like I like you, or anything, or want to join your crew, baka!"
They can take away our Nakama, but Oda will never take clown sex away from us. The bad man who won't let anyone join the crew can't hurt us if we drown ourselves in clown sex.
