(S07E04) The models take a backseat on 'Project Runway' tonight with the first client-based challenge. With $100 and one day, the contestants had to create a gala dress for Campbell's Address Your Heart Program. Their clients were all impacted by heart disease in different forms. The winner gets a bonus of their dress getting a limited run, and it will be shown during New York Fashion week with the designer.

It was nice seeing an apples to apples comparison where one color was forced upon all the contestants. The Macy's blue challenge last season wasn't as much of a comparison because they got to use several shades of blue and were paired up.

There will be an interesting guest checking in with The Doctors today -- Barbra Streisand. No, the singer/actress/director won't be talking about dry throat or stage fright or even tinnitus, an ailment she suffers from that causes an unending high-pitched ringing in the ears.

Barbra Streisand is calling in to The Doctors to discuss heart health awareness for women... and even though I've never watched The Doctors, I will today. I guess that's why and how celebrity helps causes like this. It draws attention and, presumably, I'm going to get something of value out of tuning in. I've already had my eyes opened.

So now we know why Billy Mays was so hyped in his commercials -- he used cocaine. The autopsy results for the TV pitchman confirm that he died of heart disease, but there were also traces of cocaine in Billy Mays' system from a few days prior to his demise.

There was a family history of heart disease, and cocaine can elevate blood pressure and contribute to coronary blockages. The coroner, Dr. Chrostowski, reported that "cocaine use caused or contributed to the development of Mays' heart disease and thereby contributed to his death."

If you're wearing blue to pay tribute Billy Mays, you were probably as shocked by the pitchman's death as I was. Heck, I was even more surprised by Billy's passing than I was by Michael Jackson's. The guy seemed as healthy as a horse, sporting nothing more than the slight beer gut anyone of his age that's not a fitness fanatic and lives the good life is likely to have.

So in a perverse way, some of us approaching middle age were hoping that the cause of Billy's death could have been explained by the bump on the head he got after his flight had a rough landing the day before he died. We figured it was a delayed response to head trauma, a la what happened to Natasha Richardson earlier this year.

But autopsy results, verified by Billy Mays III on his Twitter feed, showed that there was no head trauma. Mays simply died of heart disease.
