Bethesda Blog has alerted Oblivion players to an amusing and useful tutorial. The video will show you a little exploit to get rich; quick meaning in ten minutes or less. The piece is done pop-up video style with snide little comments along the way. If you are playing for fun and don’t care to be challenged, or even if you just need a laugh for the day, check out this video.

Not an unknown glitch, but the subtitles are amusing.
Glitch was fixed in the PC version I think, I assume it’s still possible in the 360 version due to this video.
I can confirm it’s working also in the PS3 version. Removes half the fun of the game, but still a great game
I guess someone at Bethesda wasn’t to happy about it, that link is now a 404.
Only scrolls work for duping. Arrows don’t anymore.
