Most people know better than to wind up their mammies, but not John Coen.

The Galway man provoked his mother with an unexpected ‘leek in your sink’ prank and captured the priceless moment on video.

John’s poor mum gets more and more frustrated when she is unable to see where an alleged leak is coming from – not realising he is referring to the vegetable in the basin.

Getting walloped with said leek seems like an appropriate punishment for this one!
