What a great idea. Not only could you save money on not buying shampoo, but you would no longer have to buy grease when frying chicken! You'd just get it from your own head!
And why not take this a step further? Why bother with soap when bathing? That's just a senseless waste. And those girl wrestling matches?....no need to add any unnecessary oil.....they could be slip-sliding away in their own body oils after awhile!
The possibilities are endless!
