:Shudder: Careful now. Giraffes have this as a natural defense: http://thehusbandblog.files.wordpress.com/2008/12/giraffe-tongue.jpg
I look at it this way, you design the world, then the PCs decide how it works. After all, they live there. If combat devolves into men slap fighting and wrestling around a lot, most opponents will be kinda good at it. If civilized society has decided that walking up to one another, shaking hands, then drawing swords etc. is the way to go, most people won't have to worry about vicious Noogie Supremacy. You picked the location of the duel, let them pick the weapon. Most of the time.
