Cook something in a Pyrex pan at 450 degrees. Remove your food, and place the Pyrex pan in the sink. Add water. Pyrex will promptly shatter of its own accord.
Someone needs to tell this to single men before they start cooking. Granted, I should have learned this sort of thing in Chemistry, but applied science in general needs to be emphasized more than it currently is.
I had to use my winter gloves to dig out the hundreds of burnt-fish-encrusted shards of glass from my sink.
UPDATE: Amy reported a similar experience from several years past, with pictures.
