...and the euphamism "Boiling Frogs."

The idea being that if you place frogs in a pool of water and raise the water temperature ever so slowly, the frogs will never notice that they are eventually being boiled alive, so they'll relax in the boiling water with complacency, as they are slowly cooked to death.

It's a common idiom with an established meaning. The behaviour of actual frogs is immaterial.

It's wrong: frogs don't do what was described.

Ostriches don't bury their heads in the sand when they sense danger.
