This is Kieran Lee.
He's a teenager who lives in Edinburgh, Scotland, and likes playing ice hockey.
This is Keiran Lee.
He's a 32-year-old English porn star.
He has shot more than 1,000 sex scenes.
He has a penis insured for $1 million.
And he has more than 150,000 followers on Twitter, where he often posts pictures of his butt.
Got the difference? OK, well for a while on Tuesday, the staff at Twitter were a little confused when they accidentally verified the account of Kieran and not Keiran.
The blue tick, which Twitter adds to some people's profiles to verify their identity to other users, appeared without warning on the teenager's account, which had a few hundred followers.
At first, Kieran was both delighted and confused.
As Kieran's bemused initial tweet spread across the internet, even Keiran (the porn star, remember?) was proud.
But the two guys were also a little bit confused.
"We knew he had the same name as a porn star, but we never knew he'd be mistaken for him," Kieran's friend Jordan Kevan, 16, told BuzzFeed News.
Twitter did not return a request for comment from BuzzFeed News on how the mix-up occurred, but the mistake was eventually rectified and Kieran's blue tick disappeared.
There's no justice in this world.
