I've spotted that domino gag before...
As sure as night follows day, the announcement of a joke competition winner is followed by a claim it wasn't original.
And wouldn't you know it? Last week's hunt for Ireland's Funniest Joke has gone the same way.
Last week, Sean Hegarty (pictured) took the title – awarded by the Hardy Har Comedy Club in Bray – for his line: 'Do you think if one Domino's Pizza place were to close down, all the rest would have to follow?'
But yesterday Darren Walsh retweeted a very similar gag he first tweeted in 2012:
If one pizza delivery company closes down, they all close down. It's the domino effect.

Of course Twitter has hundreds of variations on the same gag, too.
And Lee Mack can also lay claim to a version, saying on one episode of Would I Lie To You: 'You murder one pizza man, then you have to murder another pizza man - that's the Domino effect.'
If only there was a name for the phenomenon when one person cracks a joke like this, then others follow in quick succession…
