Returning to the UK with an empty suitcase

I've always got a full suitcase of gifts and things for the house when I go to Brazil but an empty case on the way back.
Have I missed something obvious? Is there something worth bringing back to the UK?

a couple o keys maybe

you could take my wife, she wants to back to the Uk,

A couple of new players for the premier league maybe?  Might be able to get a good mark up on them.
