Sorry folks I have only ever seen the paperclip once. He had the cheek to offer to help me type a letter once and only once!
To extinguish him forever go to "help" across the top bar and select - "hide office assistant" - result (in my case at least) - gone forever!

Next item - how do you stop it making adjustments which you sometimes want and sometimes do not want - eg. turning things into hyperlinks, capitalising etc ... immediately hit the edit button on the toolbar and choose "undo auto format/correct whatever" it will go away!
