Hi RAZD,
I found a great case in point regarding being unwilling to accept scientific definitions and to make a tidy profit.
I'm a beginning meteorite collector, and I found this ad on Ebay:
Error Page | eBay
For those unwilling to click on the link, this is a missionary working in New England who believes he has a Martian meteorite. He's trying to sell it for 20 million dollars. His sole line of evidence is a vision had where God pointed at the rock and said, "Absolutely, absolutely!" with a pen and a red dot above it. He uses that as proof that it's a Martian meteorite. Never mind that it lacks a fusion crust, is way too big to have survived atmospheric entry, and has magnetic minerals (which aren't found in Martian rocks). He's been chopping it up and selling it for $33 a gram, or about $15,000 a pound.
I've followed the story a bit, and several scientists have looked at his rock out of pity, and none have concluded it's a meteorite. However, it sounds pretty clear that he won't accept any evidence contrary to his vision. By being unwilling to accepted scientific definitions for what constitutes a rock from Mars, this fellow stands to make a lot of money.
Also, note the small jibe thrown at scientists at the end, where we're working actively to disprove God and say we came from monkeys.
