In all fairness (which isn't much):

Not too sure about how much it would save him from the heat, but even then, I find it campy. Sure, you could call it unrealistic, too, and I certainly didn't grow up in the 50s, but keep in mind that that was the era with the doctrine of "Duck and Cover" to save yourself from a nuclear attack. If he had done THAT and survived, I would have laughed so hard I would have cried.
