How bad hyperinflation can get

The remarkable story about Zimbabwean hyperinflation:

The cumulative devaluation of the Zimbabwe dollar was such that a stack of 100,000,000,000,000,000,000,000,000 (26 zeros) two dollar bills (if they were printed) in the peak hyperinflation would have be needed to equal in value what a single original Zimbabwe two-dollar bill of 1978 had been worth. Such a pile of bills literally would be light years high, stretching from the Earth to the Andromeda Galaxy.
