Television series often, inexplicably, switch nights or showcase ‘special’ episodes on evenings other than when they are scheduled to air. Normally, this wouldn’t merit a mention. But normally, it’s not one of the best shows on TV doing it.

House M.D. will air tonight at 8pm, rather than in its usual time slot of Tuesday at 9pm. The show features some of the best writing and acting on television, successfully walking the tightrope each week between humor and heartbreak. Tonight’s episode features a teen supermodel whose heroin addiction may or may not be her biggest health problem. The case parallels House’s own downward spiral into drug addiction, brilliantly explored last week when the good doc’s actions suggested he was moving beyond pain medication into something far more sinister. Such a special show deserves a special mention. Be sure to tune in.
