“A Jiffy” is False Advertising

Little Miss KnowItAll Factoid:

“Jiffy” is an actual measurement of time. The definition of a Jiffy varies from field to field and age to age, but the original definition was the time it takes light to travel one centimeter. Which is apparently 33.3564 picoseconds.  And a picosecond is one millionth of one millionth of a second.

WHICH MEANS that anyone who says that anything can happen in a jiffy is a bald-faced liar! Unless they’re talking about light traveling one centimeter. Which they’re not.
