Saw the headline and immediately assumed they’d go straight for Malvolio’s “C’s, U’s and T’s” joke. But no! They go for the F bombs.
Actually, I never really thought of it. We all know that Shakespeare could be filthy when he wanted to, but how often did he go for the F word? The examples that they give in the article (“what is the focative case? I’ll firk him!”) had never really stood out to me.
