Spontaneous Human Combustion

The Discovery Channel is showing a feature on humans who suddenly burst into flame and cremate themselves. They are just sitting there, and boom, they catch fire and are reduced to ashes in no time flat.
Swell. Now I am afraid I'll be sitting here one day and poof, all gone.
A 175-pound woman was reduced to a 10-pound pile of ashes in just moments.
What if she was sitting there, daycreaming about her new Canadian girlfriend and she got so hot she just broke into a blaze?
I better drink some ice water and start thinking about baseball scores.
And I am gonna send ice skater butt some macadamia nut cookies, potato chips and chocolate truffles.
