“Cowboys: Scrape shit from boots before entering” (sign)

“Cowboys: Scrape shit from boots before entering” is a jocular sign that has been printed on many images.
     
“And the beer-drinking crowd at the Frontier Bar—a place festooned in cattle brands and with an entrance sign that uses barnyard words to warn cowboys to scrape manure from boots before entering” was printed in the Omaha (NE) World-Herald on October 5, 2000. Similar signs are for politicians instead of cowboys.
