Can you disable the OS Update Notification thing?

If I knew what to call it I could search for it so I am sorry if this has been covered before. How the hell do you permanently get rid of that intrusive notification, updater bubble thing the pops up in the upper right of your desktop. It constantly pops in to annoy me and cover up some of tool pallets and such.

Any help to kill that thing would be appreciated. Thanks.

Further clarification, in my system prefs I disabled all the things (messages, calendars..) you can but the OS updates push through and it's annoying as hell.
