With the attention that concussions and injuries are garnering there are usually views of the situation that bring levity and humor. You can only nod your head and laugh along with the masses, and understand that its part of the process. This was the case in point for the South Park episode on this subject, Sarcastaball.
The opening of the episode does take a sarcastic look at the issue on and off the field with players, after that it just gets funny! The episode is NSFW, but good for some laughs. Click link at your discretion.
