It seemed like a good idea at the time... and I think it still is...
The teenagers who won the Schools Question Time Challenge (and are producing next week's programme) decided they wanted a Joe Public panellist - and a young one at that.
They also wanted some new-fangled internetty way of finding the right person - get 18 to 25 year olds to send in a video clip of themselves on their mobile phone.
Well, we had a pretty good response in the circumstances. It has to be said, a fair few entries never quite overcame the technological hurdle (or was it our ability to fathom how to access them?). By no stretch could you say those entering were a representative sample of the age group - but it was striking how many said they were Conservative supporters. And each assumed they'd be highly unusual to hold such views when so young. And surprisingly few green types - or is that my middle-age stereotyping expectations? Some Labour supporters - rather fewer actually expressing enthusiasm for the government - and quite a decent smattering of Lib Dems and others not yet committed to a party…
But we absolutely have to do this on merit - sticking them on the programme with four professionals is a huge ask. So we distribute the shortlist to the student producers, some now more absorbed in exams than programme planning - more technical and logistic hitches - but they start e-mailing back their views. Thankfully broadly in line with ours.
Those who almost made the final cut included a brace of Cambridge undergraduates and ranged from an Iraqi medical student to a single-mother voluntary worker.
Anyway, having got the shortlist down to four, we're now organising our own mini "Politics Idol" - run a dummy Question Time (with David D in the chair of course) putting these finalists through their paces. The aim is for one of them then to join the normal-ish Question Time panel, next Thursday and spout their views to the nation on whatever subjects come up.
I say "aim" - frankly, that's my weasel-word way of saying that if, when it comes to the crunch, none of them are quite up to it, then I still reserve the right to protect BBC One from a duff programme - and abandon the whole idea. I keep reassuring myself that it won't come to that and that taking risks (reasonable ones) is part and parcel of keeping a long-running and treasured flagship fresh and relevant.
Ask me again a week from now.
So, assuming it goes to plan and looking on the bright side, expect to see one of the following on the last Question Time of the series, on July 6th:
• Gareth Davies, a 22 year old from Leeds, who, uniquely among entrants, managed, simultaneously, to walk and talk into his mobile phone - and make good sense.
• Louise Box, who's 21, just moving to Manchester and works in retail. One of her hobbies is shouting at the telly every Thursday night.
• Matt Pollard, a student at Exeter who once got to ask a question from the audience on Question Time.
• Sarah Hajibagheri, an 18 year old gap year student who's just had a stint working for an "inspirational" MEP.
Good luck to them and to the Question Time student producers - and I must remember to send heartfelt appreciation to the regular Question Time team, who put a huge amount of extra work into this.
