If there's one thing we love more than ordinary people who dance their hearts out (see here, here and here), it's ordinary people who sing their lungs out.

So step forward, bartender Will and fitness instructor Monifa Sims. The couple have become overnight stars thanks to 'The Tonight Show with Jay Leno' and its wonderfully silly segment 'Pumpcast News' - which got them to sing their favourite karaoke songs while they were filling their car up at a petrol station.

The Sims' renditions of Bon Jovi's 'Livin' On A Prayer' and Eurythmics' 'Sweet Dreams (Are Made Of This)' are just pure and utter joy. And as a result, the video's gone viral - and they got invited on to the show to sing the songs with the live house band. Don't you just love it when good things happen to good people?
