Is this a preview for the next Zorro movie? A Decemberists music video? Someone's really bad student film? No, it's a commercial for the weight-loss drug Xenical, and it's scary in about fifty different ways.
Don't tell Rachel Zoe, but apparently the fashionably self-loathing once ingested tapeworms — sanitized and "jar packed", mind you! — as a means of getting scary skinny. Personally, we'd rather suffer a lifetime of anal leakage than host a herd of flat-bodied fish bait in our GI tracts, but hey! To each her own!
