A California couple, Will and Monifa Sims, appeared on Jay Leno's "Tonight Show" after their hysterical karaoke performance at a gas station went viral. The pair became part of a "Tonight Show" prank when they stopped at a gas pump where the popular late night show had planted a camera.

The video shows Will singing while he fills his car. An anchor on the TV screen above the pump tells him he is 'on the news' and will get free gas if he performs a song.
Will is surprised at first, but then offers to sing Bon Jovi's 'Living on a Prayer'. So, he starts to sing...but then his wife gets involved, and that's when the fun starts!

Leno said he had the Sims on the show because, 'the two were so entertaining and it was so nice to see a happy couple.'
