As ever we're looking for the unexpected on the campaign trail, and my interview with David Cameron was somewhat eclipsed by an impromptu one demanded by Chloe Green, who's a nineteen year-old student at Southampton University.
It's been number one most watched video on the election website for 24 hours now, and gets reported in this mornings Telegraph, Mirror, Daily Echo and the Wall Street Journal!
Chloe had just finished a session in the gym when she spotted the Conservative campaign bus outside, so still wearing her exercise kit she dashed out and caught him on the stairs.
When I caught up with her later she said she's not a member of any political party. But living at Bridport in Dorset she'd support the Lib Dems as the best chance of removing Conservative mastermind Oliver Letwin.
The thing that really fires her up is the chance that other people like her might not be able to afford to go to university under the Conservatives.
While the rest of us were in hard negotiations to be granted an extra question on this subject or another Chloe managed to engage the party leader in a detailed debate which it's well worth setting down here in full.
If you watch the video which I'll put at the bottom, it's clear this was a running debate on the hoof, which is never easy.
CHLOE: What about me? If I didn't have government support I wouldn't be here. DC: Well I want government support, we support government support, we think it needs to go on, we need to go on having bursaries for instance...
CHLOE: Really?
DC: Yes, who's told you we don't support bursaries - don't believe what you read in Labour leaflets I promise you!
CHLOE: I'm not voting Labour, I want real change
DC: No no, you won't get real change, if you look at what the Liberals are saying, it's quite important, they're going to get rid of tuition fees. 
Read the small print - they aren't going to do it for 6 years. 6 years! I think that's a complete con for people. I think it's better to be upfront as I am and say we can't get rid of the tuition fees and the top-up fees because we want good university places. We must always help people from lower income families to go to university that's why we keep bursaries and expand bursaries. But don't be fooled by people who say they'll get rid of tuition fees. We can't afford it when we have this big budget deficit - the numbers just don't add up.
CHLOE: No that's fine but about bursaries - are you definitely going to keep them?
DC: Definitely keep bursaries, and look at ways of expanding bursaries. Do you know today there are 80,000 people on free schools meals. Do you know how many of them get to Oxford or Cambridge? Just 43 - I think that's terrible in our country.
CHLOE: I don't think that's going to change with your government though.
DC: Well it will change with our government 'cos we're going to improve the state of secondary education.
CHLOE: What about comprehensives?
DC: Well that's what a secondary school is. We believe you've got to open up the system and allow new schools in you've got to have greater diversity, choice, competition, excellence in our schools. The ones who are actually arguing for real change in secondary education are us, it's the government and others who say oh keep things as they are, don't break open the system. We're really quite radical, I was at a rally in Yorkshire yesterday with parents who want to establish a new school, an excellent new community school, so their kids get a really good start in life. It's the Conservatives who have very radical new education policies 'cos we're not happy with the status quo, it's not right that opportunity's so unequal in our country. OK? Good to see you.
CHLOE: I don't believe you.
DC: Well, I do my best. Nice to see you.
On Twitter and the blogs too Chloe has been an instant hit, just search for the hashtag #chloegreen. She tried to say she was embarassed by all the attention when I caught up with her last night, appearing on the BBC Campaign Show, where she was a star for a second time.
She did take a bit of abuse on-line for not understanding that a Comprehensive was a secondary school. She's in the first year of an English Literature degree and wants to be a writer, not a journalist.
Some have said David Cameron also comes out of the encounter well. His explanation is patient, honest and engaging. It's a way of operating that I've seen over seven or eight years as he built up to this push for PM, but which seems to have failed to come across in the TV debates.
So on reflection what is Chloe's opinion of Cameron? She remains as unconvinced as she was in the video.
"He's very slippery." She says. "He was avoiding the question. He just told me Labour were talking rubbish, as he always does."
