People going crazy trying to work out man's 'joke that only one other person on entire planet will understand'

People are losing their minds after trying to work out why this guy has shared a 'joke that only one other person on the entire planet will understand'.

YouTuber Obesus has left two million people brain f**ked with a short 17-second clip.

Whilst many have shared their theories online as to what the joke could be, no one has got it right so far.

Taking to YouTube, the content creator shared the quip that only one of his mates would understand.

He said: “All right there's the ultimate inside joke, there's only one person, one person on this entire f***ing planet that knows what this joke means and here you go.”

And the in a deep voice, he says the punchline: “Judi Dench.”

Why the James Bond actor is the brunt of his joke, no one knows.

In the comments, he further added: “I’m sorry to say that nobody has figured it out yet, should someone figure it out I will update this comment with a full explanation.

“Edit; I have edited the title to make it clear that there is one person other than me, that actually gets the joke.

“Also, the joke isn’t that there is no joke, there is a legitimate inside joke between me and a friend, and it’s been a joke for almost five years now. There, that is your hint.”

Though I'm grateful for the 'hint', I still don't have a bloody clue - and there's no further explanation in sight so it seems no one has figured it out yet.

Sharing their reaction in the comments, one person wrote: "This is the type of video to get recommended to 40M people after seven years."

"I clicked on it to find out if I was the chosen one. I have once again been disappointed," a second penned.

"Plot twist: there is no 'other friend'. It’s just a social experiment to see how much traction that a simple lie could bring his video," a third theorised.

"This is now going to become an inside joke for some random group of friends after it gets recommended," added a fourth.

While another reckoned: "When people say 'Judi Dench' in a deep voice, it’s a fun way to imitate how someone might exaggerate or emphasise her name for humour.

"It’s like a playful inside joke or a way to make her name sound more dramatic or funny when spoken aloud."

Hopefully one day, we will find out what he and his mate are laughing about.
