This post is part of a series on celebrity spokespeople who ended up doing serious harm to the brands they were hired to promote, or vice versa. See how we rank the 20 top spokesperson fiascos.

Okay, to begin with, I should be completely honest: I'm a definite Kirstie Alley fan. I've watched her since the beginning, since she walked into Shelly Long's shoes on Cheers and took the show to a whole other level. I watched as she began to mature gracefully in Summer School and the Look Who's Talking movies, and even stayed with Veronica's Closet for way longer than I should have. Over the years, I watched her bloom, blossom, expand her horizons, umm...

Okay, yes, I also watched her gain a lot of weight. Somewhere between the overripe evil of Gladys Leeman in Drop Dead Gorgeous and the impressive avoirdupois of Fat Actress, Kirstie Alley definitely put on some serious pounds. When they started shooting her in low light with dark clothes, I had my suspicions; when Fat Actress debuted, there was no longer any doubt.

Still, I was rooting for Kirstie, and I was happy when she got a gig working for Jenny Craig (a division of Nestle, VTX:NESN). While I'm not sure that weight loss is for everyone, I have no doubt that, for Kirstie Alley, it meant the difference between being gainfully employed and using her royalties from syndicated TV shows to buy herself an island and a bunch of muumuus. I hoped that the marriage between Kirstie and Jennie would thrive and be, if not fruitful, at least healthy.

Former Vice President Al Gore is doing quite nicely staying out of the current political fray.

Generation Investment Management Ltd., which he co-founded with ex-Goldman Sachs Group (NYSE: GS) banker David Blood in 2004, attracted nearly $5 billion to its main Global Equity Fund and is probably restricting inflows into the fund next month, according to Bloomberg News.

The fund has some pretty high ideals according to its Web site: "We focus on the economic, environmental, social, and governance risks and opportunities that can materially affect a company's ability to sustain profitability and deliver returns. Our research plays an important role in forming our views on the quality of the business, the quality of management, and valuation."

So how does that translate in the real world? Al Gore isn't providing performance details, according to the Bloomberg story. It's kind of weird for Gore to be so mum considering that its biggest holding Novo Nordisk (NYSE: NVO) is up more than 60% over the past year in U.S. trading.
