i 've got a right-little chamber pot rigged up so i do n't have to use the head , but i still go to the head sometimes when i know there 's no one in there and go up to the trough as if i 'm properly rigged out to use it , and i wait till i hear someone trompin ' in and then do the shake-and-wiggle action the boys do and cinch my pants and leave , havin ' furthered the deception .
