Spitting - It's a national pasttime used to prepare for the return of Taiwan to China - a Sichuan (who else?) once commented that if China wanted to return Taiwan - they don't need to send weapons - everyone in China will just rush to the east coast and spit in the ocean (environmental hazards aside) which would tidal wave the island leaving it "clean" and sanitized. US has no defense against the mass spit weapon.
Aside from that - I really want to go poop in front of some of my dog-owning neighbors' doors - y'all know why.
