When his fellow villagers disgustedly waved off his amazing tales of howling adventures and intrigue during his trip as an
ambassador, Will Rogers
indignantly snorted that he hoped that a building would fall in on him if he'd "padded the facts" at all about his recent political adventures, and a huge brick chimney
immediately did collapse and shower him with bricks and powdery mortar-dust (he wasn't hurt -- no worries). Kind of a crude and "extreme" polygraph-device, but it did indeed show that Will had evidently been stretching the truth somewhat.
