Chaz

I sometimes watch old "Flipping Out" episodes even though the lead guy is a jerk.  There are some seasons where they do some work for Chaz Dean, who may be even more annoying in his own way.  I vaguely recall him constantly being on an infomercial, perhaps with Alyssa Milano, about 15 years for his Wen line of hair care products.  The supposed main advantage was that the shampoo didn't lather, which doesn't seem like a great thing.  Tens of thousands of people also complained that it caused their hair to fall out, which certainly seems like a bad thing, and led to a big class-action settlement.
