The group of Europeans and a solo Indian were arguing on whether wiping was more hygienic or washing. The Europeans claimed that wiping was better because it does not require one to get in direct contact with the shit.
Half an hour later.
Said the Indian- We are done with dinner, lets wipe the plates clean and put them away.
Exclaimed the Europeans- What? wipe them clean? We need to wash them clean.
Retorted the Indian- That's why we wash, not wipe.
