John Humphrys on Facebook

Pretty much every morning I listen to the Today programme while I lie in bed drinking tea. I switched on today in the middle of an item about Facebook. The report was fine - my take is that it's a slow time for news so we're getting lots of Facebook items (they're easy to do) - but the best bit's back in the studio after the report. John Humphrys is handing over to the sports reporter Gary Richardson, and asks him if he's on Facebook -
JH: Are you on Facebook, Gary?
GR: No. Are you?
JH: (The briefest of pauses) What do you think?
That'd be a no then.
