Boys seem especially attracted to mud. We would look for puddles to ride our bikes through at top speed when I was a boy. The trouble is we could not do that without getting dirty. Our moms were not always happy!

 But he that is joined to the Lord is one spirit.
 Flee fornication. Every sin that a man does is without the body; but he that commits fornication sins against his own body.
