You're right; Wallace was lying about the bread-ironing! So I'm quite surprised to hear that you actually know people who do that. (Mitchell was quite disappointed to find it was a lie. 'I was making a mental note to try that!')

Brooker is constantly affectionately insulting Mitchell. It's rather lovely. If you are becoming interested in the pairing - and I heartily encourage any such interest! - you may also want to read the Unbelievable Truth report I just posted from Monday, which also featured the two of them.
