There are, oddly enough, apps in Apple's App Store that have absurdly high prices while doing nothing of value (or nothing that isn't already done by another cheaper app). Sometimes they're near-clones of popular apps, probably hoping that people are stupid (safe bet) but Apple usually shuts those down when people complain.

So go for it, Mark! What's the worst that could happen? (That's a rhetorical question, btw, not a challenge.)
