A grandfather-of-eight spooked his loved ones by speaking to them beyond the grave at his own funeral .
Shay Bradley - whose late mum Susannah Mulligan was from Glasgow - had his family and friends in fits of laughter after he planned the ' funeral prank' before he passed away.
The dad-of-four can be heard seemingly banging on his coffin yelling "let me out, it's dark in here', as stunned mourners surround his open grave in a south Dublin graveyard.
The viral video shows mourners lined up around the open grave who are just finishing up applauding as bagpipe music begins, reports Dublin Live .
The music stops and a man can be heard saying "hello" while ferociously knocking on what sounds like the inside of the coffin.

Shocked family and friends begin to look around in disbelief as renowned joker Shay begins to roar "let me out" from a pre-recorded message being played through a speaker.
The tears soon turn to laughter when Shay can be heard saying "it's dark in here".
Shay continues: "Let me out. I can hear you! Is that the priest I can hear? I'm in the box, can you hear that?"
He finishes the prank by serenading the crowd shortly before the video ends.
His daughter, Andrea posted the video on Facebook saying: "My dad's dying wish, always the pranksters, you got them good Poppabear and gave us all a laugh just when we needed it!! I will love you forever #shayslastlaugh ."
She added on Twitter: "It was his dying wish that we played this at his funeral. What a man, to make us all laugh when we were incredibly sad. He was some man for one man. Love you forever Poppabear."
Andrea said: “My dads mum was Susannah Mulligan from Glasgow and she married Jack Bradley who was a butcher from Dublin. It’s been a complete whirlwind - amazing and also very sad. We couldn’t believe it when we heard him speak from the coffin. We were all in hysterics laughing. My brother recorded it with my dad about a year ago and said you have to play it.” He told him ‘Let your mam hear it first but don’t let her say no. The grandkids and us heard it first but no one else knew apart from his immediate family. It’s made it so much easier for us with this prank. He was always joking through life. We’ve had absolutely tons of people contacting us.”His wife Anne said: “He was in the army in his early days and worked in his family butcher shop for a while but he was a salesman and sold everything and anything though never coffins. He always felt sorry for undertakers because he thought how could they ever have a laugh.
He was sixty three and diagnosed with illness three years ago and made the recording around a year ago when my son popped into lunch to see him one day.
He always called himself Famous Shamus and he’d be so happy with this right now. In hospital he loved the nurses and all his careers and he was a larger than life character. He loved life and his family. I’m totally overwhelmed.”
