Come in handy -- get it? Like your wiener when you're peeing! "I don't touch it when I pee." DON'T TRY TO JUSTIFY NOT WASHING YOUR HANDS.
This is a chart from the Boy Scouts of America that offers a general indication of your dehydration based on the color of your urine. I don't know what the hell is going on at the top of the chart, but I've never pissed peach before. Just remember: if your pee's brown you're in serious trouble. Ooooooooooor can't tell the difference between your penis and b-hole.

Thanks to Clark, who claims he didn't learn anything in the Boy Scouts except how to tie knots. Me? I LEARNED HOW TO SURVIVE (my troop accidentally left me on camping trip).
