A simple gas-pump prank ends up turning into one of the funniest karaoke sessions you'll ever see, in this viral video.

It begins as an installment of The Tonight Show's "Pumpcast News," where gas customers are surprised at the pump by a news anchor who can see them from the station's television screens.

But in this case, they prank just the right person: A man who delivers a killer impromptu karaoke rendition of Bon Jovi's "Livin' on a Prayer." And that's not all — his wife then does her own spot-on performance of "Sweet Dreams" by the Eurythmics.

This is truly must-see stuff and the YouTube video, above, has gone viral for good reason. Check it out for yourself; then let us know what you think in the comments.
