When we were down at MD Anderson Cancer Center in Houston the hotel's shuttle stopped at Houston's Restaurant to pick up a trio of middle-aged women who had taken great advantage of happy hour. Even though this one woman claimed to be a fifth-generation Texan, her family came to Texas from Mississippi.
She complained about the lack of intelligent men at the restaurant's happy hour and this one man in particular.
"He couldn’t tell sheep (dung) from a cotton seed," she commented, which struck me as very funny. I had never heard the term before.
