There's thinking on the spot and there's literally just saying the first thing that comes into your head.
When faced with a member of the Gardaí because you were caught on the phone, neither option is going to turn out well.
But, the latter is definitely not going to do you any favours.
This headline from the Meath Chronicle has crept back online once again as it still holds the title of worse excuse of all time.
A Navan resident by the name of Morgan Carr received a fine for being on his mobile phone while driving
Prosecuting garda Robert Conway told the court that he saw Carr using his mobile phone when he was driving an oil tanker.
When stopped - we shit you not - Carr was found holding a stapler to his ear and told the Garda that he had mistaken the everyday, carries it around in his back pocket just in case, stationary item as a mobile phone.
As you can imagine, that line didn't quite go down a treat with the Garda in question and Carr had to pay a €250 fine.
The picture has resurfaced again on Reddit, with commentators saying that it's up there with one of "the worst excuses ever seen".
Another said that it was a classic Irish response and that the Irish will "argue and use any excuse to try and avoid responsibility."
Is this the worst excuse you've ever seen? Or do you have a better one? Let us know in the comments.
