What glitches can you use to get higher levels in oblivion

If you haven't done it already, on the first mission for the Dark Brotherhood when you are to assassinate Rufio, he will remain asleep for a majority of the time and will not wake up unless you interact with him. So just go into sneak mode and walk around him while he is sleeping and your sneak skill will increase rapidly. A way for lockpicking is obtaining the skeleton key from Nocturnal's Shrine and auto attempting Very Hard leveled locks. This will take forever to unlock and will boost your lockpick skill without losing any lockpicks because the skeleton key is unbreakable.
