As I was flipping channels from TMZ to The Real Housewives of New Jersey (I love the way they tawk), I accidentally stumbled upon CNN. Some talking head said something about a senator "flexing his political muscle". Since I obviously have no concern for national politics, you're probably wondering why this caught my attention. Because you can't flex a muscle. You contract a muscle, and you flex a joint. I suppose Mr. TV Guy can be forgiven, but if you want to see that little vein in my temple bulge, sit me next to a so-called health professional who misuses the term.
