The 'clown craze', whereby people don white masks and red wigs and attempt to scare others, has expanded from the United States to Europe.
It’s reached a point where men are dressing up as superheroes and chasing those who dress up as clowns. Oh 2016, we will remember you.
Like every fad, it will probably soon pass. People will realise that pretending to be a crazed clown really isn’t worth the criminal record. We hope they will, anyway.
Conor McGregor certainly has less things to worry about at the minute than scary clowns.
The UFC featherweight champion is preparing for a fight with Eddie Alvarez at UFC 205 in November. It’s a big one, too - McGregor is attempting to become the first two-weight champion in UFC history.
And he’s not about to let a clown get in his way.
"I'd slap the head off him"
The Notorious discussed the craze while speaking to the Lad Bible. To anyone that has plans of trying to scare McGregor, stop right now.
"Yeah I've seen people dressing up as clowns or something,” he said.
"If one came near me I would slap the head off one.
"I mean you see one jumping out in front of you screaming in your face, I'd slap the head off him.
"I'd take the mask off him and stick it up his a***.”
The 28-year-old added: “Just don't come near me in a clown mask. Don't come near me period or I'll slap the head off you anyway but if you're in a clown suit I'll slap the head off you even more so."
He won't hold back.
McGregor will look to become lightweight champion when he takes on Alvarez in Madison Square Garden on November 12.
The naturally-confident Dubliner is predicting a quick finish.
“My fist is bigger than his (Alvarez's) head,” McGregor added. “I think I will put him away with a shot and it will be devastating.
"I think it will be an early night."
Clowns, UFC fighters, you name it. McGregor’s knocking them all out.
