Not in a liquidity trap

Hyperinflation in Zimbabwe, the former Rhodesia, was a quadrillion times worse than it was in Weimar Germany.

That's via Jason Kottke (source here).  There's also this bit:

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.
