Let me introduce you to a couple of wonderful new inventions dude. One is called
Anti-Perspirant!!! You rub some underneath your armpits, and *VIOLA*! No more stink!!! The second is called a
SHOWER!!! It allows water to pour on you so that you can wash away all the dirt and grime and sweat that causes B.O.
*cheesy Infomercial voice* - Try it! IT WORKS!!!
