I just come out of the woods and my boots are really dirty and muddy - good that I've my slave's fresh washed white shirt hanging in the car ;-) I throw it in the dirt so I can stomp and rub my boots clean on it. Some of the dirt is really sticky so I grab the shirt and use it as a cleaning rug before I throw it back on the ground. When my shoes are somewhat clean I get into the car and "accidentally" drive over the shirt a few times ;-)
