Theiving Bug: Easy Money:

This bug is virtually unheard of but is very handy. Here is a great way to use it.

First of all find an artifact that can be sold to the mournhold museum of artifacts,eg:staff of magnus,lords mail,goldbrand.
Sell the item and get 30,000gp
Once sold find the item inside the museum and jump onto the stand that the artifact is placed on
Go into first person view and look directly down on top of the object
Make sure that when you jump the name of the object is still visible
Jump and when you reach the maximum hieght of the jump you will hit the cieling and stay there for a fraction of a second,when this happens press A to take the object.
The game will not register you on the same floor/level as the guards and so they wont realise.
This works about 90% of the times tried and on about 90% of the objects in morrowind.
Try it on the winged twilight soul gem on the top floor of the mages guild in balmora for a free 60,000gp worth of stuff.
