TLC's My Strange Addiction is back for a fourth season, and that is terrific because it such a hilarious show. On it, nothing is sacred, not even the concept of addiction, which is stretched to include things that you don't need a degree in addicitionology to know are not real addictions—if growing one's fingernails and toenails are addictions, they are the slowest release capsules possible. This may be too irreverent and insensitive for some, but I read it as media criticism: Reality TV is not the best source of addiction information. At times, though the show deals with real people (presumably) telling their true stories, it reads as parody.
