When an Taoiseach Enda Kenny's not tirelessly campaigning for a YES vote in the Seanad referendum, apparently he likes to photobomb. 

If the following picture is to be believed, Mr. Kenny ruined what could have been a lovely photo of two friends at Sunday's Ladies Football final between Cork and Monaghan.

Saturday's All-Ireland hurling final replay by reaching out with a crazed expression on his face. 

Maybe ease up on the full sugar Coke, Enda?

But Enda isn't the first notable figure to take part in generation Y's photo-ruining phenomenon. Here are a few of our other favourites:

Malia Obama ruins a moment between her all-powerful mum and dad

All Sasha wanted was a cute memento of her parents sharing a quick peck on the lips during Barack's second presidential inauguration. But all Malia wanted was to watch the world burn. 

British rugby star gives David Cameron bunny ears

Britain and Irish Lions centre Manu Tuilagi kept it old school when he gave Prime Minister David Cameron bunny ears at a photo shoot at 10 Downing Street. 

This wasn't the first time Tuilagi showcased the sheer depth of his maturity: two years ago he was fined £3,000 after jumping out of a ferry in New Zealand. 

EastEnders actor Sid Owen accidentally photobombs Chris Brown at Grammys pre-party

What expression is Chris Brown making in this picture? And why is the guy who played Ricky Butcher in EastEnders there? And speaking of which, how on earth did he wind up at the Grammys? TOO MANY QUESTIONS.

(Apparently Owen is friends with Adele, who somewhat less surprisingly also happened to be at this year's awards.)

Paul McCartney: the original photobomber?

We don't know if it's the earliest, but McCartney's ruination of his bandmate George Harrison's picture while two fans show complete disregard for his personal bubble is our absolute favourite.
