10. Billy Madison
Estimated worth: $200M
He's not the sharpest knife in the drawer, but Billy earned his high ranking after graduating high school in a marathon session and becoming heir to the Madison Hotel fortune.
9. Dr. Evil
Estimated worth: $500M
Thanks to Number Two's investments, the bad doctor had a bankroll big enough to pay for a high-tech lair and a miniature replica of himself.
8. Gordon Gekko
Estimated worth: $650M
This perfect symbol of '80s capitalism made the stock market his bitch, taught us that greed was good and rocked a pair of suspenders like no one else.
7. Arthur Bach
Estimated worth: $2B
The only reason our favorite alcoholic isn't higher on the list is that he chose to penetrate Liza Minnelli.
6. Professor Charles Francis Xavier
Estimated worth: $4B
The most altruistic guy on our list funds an institute where he trains young mutants to battle Magneto.
5. Thurston Howell III
Estimated worth: $5.7B
Without the blue-blood attitude that Thurston brought with him, life on that deserted island just wouldn't have been the same.
4. Bruce Wayne
Estimated worth: $6.5B
If losing your parents gets you a tech company, a side career fighting crime and a bona fide manor with a cool cave, then you've made out pretty well.
3. Scrooge McDuck
Estimated worth: $8.2B
Does your palatial Duckburg estate include a mansion that has a giant room set aside solely for the purpose of swimming in gold coins? Yeah, we didn't think so.
2. Montgomery Burns
Estimated worth: $8.4B
Springfield's power-plant owner once asked, "What good is money if you can't inspire terror in your fellow man?" We agree.
1. Prince Akeem
Estimated worth: $15B
What can we say? There's just no beating royalty. This prince of Zamunda might have pretended to be a pauper when he visited the States, but he's old money through and through.
