True, but even some of the counterexamples have counterexamples of their past behavior. Concussions are complex brain injuries that can be (and often are) personality altering. Organized sports leagues, including MMA, will go to great lengths to make sure the transgressions of their star athletes are swept under the rug.
I remember being confused after being handed some wooden disposable spoons at a local screening about 7 years ago. The person handing them out explained it to me, and suddenly I started noticing how obvious the spoons were. I think I had watched the movie a handful of times before, but never really paid attention to the backgrounds unless it was one of the outdoors scenes that were obviously filmed on a soundstage.
I was coming here to say this. Truly a disappointment that the Pentel Twist Erase GT is not included as a choice.
