Right after a dragon attack I caught him getting ready to relax himself by sitting down on a bench and uploaded himselfhttp://i1096.photobucket.com/albums/g322/Raidensama/Skyrim/TESV2012-02-2622-39-02-83.jpgand started drinking away.
IMO one of the positive ways to use glitches for RP reasons

I hope it doesn't get patched... Instead let the dragonborn communicate with him. Maybe ask him to be a follower? or better yet be creative and add a few dozen extra quests.
Edited: Added an additional word.
