I found this strangely watchable. For those unfamiliar, it's a show on BBC2 presented by a semi-professional poker player. She also wrote a book about her attempt to make the greatest hardcore porn film ever (this is my New Year's resolution). Anyway, the challenge is for the public to find the true meaning and origin behind select words like pear-shaped. I never knew Naff stood for Not Available For Fucking. Wasn't there a brand of coats in the early 90s called Naff? I vaguely remember kids at my school wearing them....well, at least people knew they weren't available for ...erm...fucking.
