"This brush will self-destruct in five seconds..."

My favorite hair brush has just self-destructed. And it's not even like I was brushing myself with it.

I brushed my hair, which was no more tangled than usual, and probably less, and put the brush down. The next time I touched the brush, most of its teeth (bristles, whatever) just fell off. Felt very surrealistic. I think I am traumatized for life now and am going to see nightmares involving Dali landscapes and toothless brushes for the rest of my natural life.

The only reason I can come up with is that it was a super-secret science-fiction self-destructing brush.
