As far as you can throw it, baby, and there ain't much gravity on Pluto.
How many pringys are in a dingaloo?
The Altairian Dollar has recently collapsed, the Flanian Pobble bead is only exchangeable for other Flanian Pobble Beads, and the Triganic Pu has its own very special problems. Its exchange rate of eight Ningis to one Pu is simple enough, but since a Ningi is a rubber coin six thousand eight hundred miles along each side, no one has ever collected enough to own one Pu. Ningis are not negotiable currency, because the Galactibanks refuse to deal in fiddling small change. From this basic premise it is very simple to prove that the Galactibanks are also the product of a deranged imagination.
If a Plutonian went out on town and wanted to have his baccaca really waxed, how much would that set him back? I mean first class, not by some toothless gorgamite.
Luckily, this question is not answerable, because Plutonians outlawed possession of a baccaca -- waxed or not -- in the Great Special Hoopty Pants Revolution of 3074. Now, all baccaca are removed from the bodies of all three Plutonian sexes, and held in little jars for checkout provided the Plutonian has the proper forms and signed licenses -- which such forms and licenses are officially banned by the Great Hoozit Paper Form Destruction Act of 2871.
