Workin’ can make you stiff. Not workin’ can make you stiff. Exercisin’ or not exercisin’ can make you stiff. Sleepin’, couch potatoin’, computerin’, road trippin’ and insults can make you stiff.
Being made out of concrete can make you stiff, too.
Why are workers called stiffs? Some sources say it’s because people who work uninteresting, low paying jobs get stiff at the end of the day. They are tired. Maybe it means they are getting stiffed by their employers. Then they’d be “workin’ stiffeds.”
We all work. We all get stiff. Fortunately, we aren’t made out of concrete.
