Sarah Palin has done "that ice bucket water dump thing," and you gotta hand it to the former vice presidential candidate

Sarah Palin has done "that ice bucket water dump thing," and you gotta hand it to the former vice presidential candidate -- she sure knows how to keep her viewers in suspense.

In one of the latest ALS "ice bucket challenge" videos, Palin channels actor Patrick Stewart, who wrote a check for charity and used the ice from a bucket to make himself a stiff drink. Except in this case, Palin's beverage of choice is a Diet Dr. Pepper.

"Hat tip to actor Patrick Stewart for reminding everyone with his video that the donation is the most important part of the #icebucketchallenge, not the frivolous water-tossing theatrics that those of us who are more thoughtfully serious choose to forgo," she writes in the Facebook post accompanying the video.

"I'm too old for this," Palin says in the clip. "C'mon, at this stage of my life, in my career, aren't I a little too prim and proper for all that ice bucket water dump thing?"

But just when you think Palin's about to make it out of this challenge warm and dry, she ends up soaked anyway, thanks to someone off-camera with a much bigger bucket of ice water than the one on her desk.

Palin was apparently nominated by Wasilla's Arctic Cat retailer, which sells snowmobiles and ATVs. And since no soaking is complete without a challenge to someone else, Palin had a couple of nominations of her own: former senator and secretary of state Hillary Clinton and Sen. John McCain (R-Ariz.), Palin's 2008 running mate.

In the Facebook post, she challenges her husband, Todd, as well.

That ice bucket water dump thing has been used to raise money and awareness for amyotrophic lateral sclerosis, a.k.a. Lou Gehrig’s disease. On Sunday, the ALS Association said it has received $70.2 million in donations so far this year thanks to the viral challenge, compared with $2.5 million during the same period last year.

Participants aren't expected to donate solely to the ALS Association -- any ALS-related cause is a good one. Palin made out her check to the Pete Frates #3 Fund, named for the former college athlete recently diagnosed with the disease.
