Double your pleasure with Oblivion dupe glitch
Cataloguing the glitches in Elder Scrolls IV: Oblivion is getting to be like counting Tribbles. This trick allows you duplicate hundreds of items easily:
All you have to do to duplicate an item hundreds of times is to draw your bow and pull the trigger button, but before you release the trigger button, hit B to enter your items list, change the types of arrows you are using, and then select the item you want to duplicate and drop it. exit out of your item list and let the trigger button go to shoot the arrow, and your items fall out of the sky.
Video proof here. Each time you duplicate an item, it costs you 200 MS points. Just kidding.
