A simple Tonight Show gas pump prank took a sudden, unexpectedly hilarious turn last week as it became a karaoke session - and a classic one at that.
The show's "Pumpcast News" segment involves news anchor Jack Rafferty directly addressing customers at the pump until they realize it and get freaked.
Only this time, when the customer realized he was being spoken to by the news guy on TV - who had been complimenting him on his singing - he ran with it.
He proceeded to perform a killer rendition of Bon Jovi's "Livin' on a Prayer," and was later joined by his wife on "Sweet Dreams" by the Eurythmics.
The '80s never sounded so random and good.
