This brother-sister pair looks like they've got quite the sibling rivalry going on.

20-year-old Dale is always tricking and scaring eight-year-old Shiann – and Shiann's decided she's finally had enough.

This video, filmed in Monaghan, Ireland on November 17, shows what happened.

Orchestrating the prank with the help of her mother, Shiann hid in the corner of the room while Dale came downstairs to show off a vanishing trick. Shiann then then quietly closes the door behind him.

"I will disappear in three... two... one," Dale announced as he held up a cloth.

He then drops the cloth and turns to run out the room, slamming hard into the door that he didn't realise was shut.

Dale's head and knees were sore after the prank, but it was all in good nature as he agreed to let his mother share the video online and admitted to Shiann that she had "got him back very badly".

My son (20) Dale is the victim to my daughter (8) Shiann' s prank..
My daughter told me that her brother Dale showed her a disappearing trick and she wanted him to show me...she said mammy you call dale down and ask him to show you the trick and I will hide behind the door and scare him.. I asked her what was she going to do because he gets very annoyed very easily.. she then said when he comes in and starts to show you the trick I will jump out but as the was videoing him doing the trick she decided to close the door so when he went to run out he would hit the door but she couldn't stop laughing because he actually more or less bounced off the door and then he got angry because he didn't know she was even there and he now has a very sore head haha... I asked her why she did that and she said because he is always scarring is and doing pranks on us mammy and he deserved it.. sorry but it was so funny..
