Christmas carols aren't meant to have the lyrics "revenge is like the sweetest joy, next to getting p****."
But that's what happened at a Sri Lankan church when a helper accidentally printed out lyrics to rapper Tupac Shakur's Hail Mary instead of the traditional Christian prayer.
Churchgoers were settling in for an evening of carols and prayers, but one attendee noticed the error straight away.
"A lot of people were in shock as whether it was a joke or someone would actually rap the song," Andrew Choksy, who attended the service, told CNN.
"A few of the older ladies in front of us could not stop looking at the printed booklet."
