WATCH: Nate Diaz was a guest on Conan last night and guess who crashed his appearance
Conor McGregor just couldn't allow Nate Diaz to enjoy his time in the spotlight.
We're used to seeing 'The Notorious' rule the roost during media tours leading up to big pay-per-view events but it was his upcoming opponent who appeared alongside Conan O'Brien on Tuesday night.
Diaz was enjoying a solid appearance when the show's host sprung a video message from a certain Irishman on him.
And it's safe to say that McGregor added to his litany of memorable quotes as he took the mick out of Diaz's choice of attire.
"I just hope he's not up on that stage wearing that stupid black t-shirt he's never out of," McGregor said.
"The boy's been wearing that same damn t-shirt for the last 20 years or something.
"I'm taking this contest very, very seriously. I've flown in specific body types to replicate Nate's skinny, tall frame.
"The boy won the lotto the last time. He knows it, I know it. Well, August 20 I get my revenge and I look forward to it."
