What was your dream job as a child? There's no prizes for guessing what Warren's was!
As part of a new BBC radio series, cunningly called 'Dream Jobs', Warren gave an interview about how exactly it works - and what skills you might need in order to get such a job (hint: build a lot of LEGO!)
The interview is available now at the BBC website, via this link so if you're interested - please take a listen! It was also broadcast on Radio 4 Digital early this morning - but seeing as early means 03:40 in the morning I'm guessing you might prefer to listen online!
