Er...

Sometimes on the 'Net I come across people saying things like:

I'm sure you've heard the stories about the lady who was in a rollover accident, how her baby was trapped inside. With surprising strength, this 110-pound woman managed to shift the one ton vehicle and save her child.

Frankly, I've never read about any of this in the news, nor have I seen any valid references to any news articles that documented things like this. Is this just some stuff "newspapers" like the National Enquirer made up, or is there there some truth to this?
