Two guests' names were mixed up on Clare Byrne Live and Twitter loved it
Economist Dan O'Brien and Social Democrat TD Stephen Donnelly were among the guests on Claire Byrne Live this evening to engage in a debate on the new Dail term.
The two men - who it could justifiably be said look somewhat similar - both wore open-collar white shirts on the show.
Their likeness was even highlighted by Mr Donnelly before the debate as he tweeted a picture of a pair with the comment "spot the hidden mirror".
However, that didn't stop Mr O'Brien being wrongly credited as Stephen Donnelly on the show's captions.
Although the error was quickly corrected, viewers of the show took to Twitter and had a field day.
"More unnerving than Cronenberg's "Dead Ringers", wrote one user.
"Is Dan O'Brien Stephen Donnelly's long lost Brother?" wrote another.
Here's just a selection of more of the comments.

Really dangerous for @ClaireByrneLive to have Dan O'Brien & Stephen Donnelly on at the same time as naming them incorrectly just showed!!— E F Fanning (@EFFanning) May 9, 2016
