showering every day just makes ya feel dirtier when you don't because by showering every day you strip the natural oils out of your skin and then the production rate increases. therefore, you're all greasy on the second day, whereas if you shower every other day...or shower every day but only wash your hair every other day...you won't get gross and oily as quickly

I'm not defending dirtiness though, if you stink, you stink. ifyou're filthy, you're filthy...no excuses, be clean.
