Footage of a prankster pulling a joke on his 80-year-old Granny has gone viral after a two-part video was shared on social media last night. 

Kevin Tinney, 24, has been described as an "absolute joker" by his cousin, "always pulling pranks on Granny and his Dad".

Kevin's cousin Jamie Comaskey described the relationship he has with his Grandmother as "hilarious" and that the pair are "always making each other laugh".

The 24-year-old phoned his Granny yesterday afternoon asking her to cover his tracks as he secretly joked he had been caught by police speeding.

He asked her to lie on the floor for him until he arrived at her house.

After bursting through the door and filming the prank, Betty Cantley - who apparently enjoys a wee venom on a night out - soon realised that her grandson was pulling her leg as she shouted: "Are you having me on!?"

The video has since raked up thousands of views are shares since being posted at 11am last night.
