ZM hosts Jase and PJ have totally lost it as their 52-hour marathon comes to a close

ZM's Jase and PJ are broadcasting for 52 hours and have lost the plot.

Sometimes a good idea is actually a really bad one, as evidenced by the state of ZM's Drive show hosts Jase Hawkins and PJ Harding.

The pair are on the home stretch of a 52-hour long live radio marathon, due to finish at 6pm, and it's fair to say they've come undone.

PJ's having out-of-body experiences and mistaking balloons for human beings, while the crew are commenting on how Jase is "scaring me a little bit".

The overall sentiment? "I can't believe we've done this again".

That's right. This is the second time they've done this. The radio hosts embarked on a 51-hour marathon in April, 2015 and this time decided to one up the effort by adding an extra hour.

That's 52 hours in a studio, on air and on Facebook livestream with no sleep, no real breaks, and the requirement they speak after every two to four songs so we know they're still there (and still awake).

The worst part is there's no actual reason. Last year they did it for charity and with a Guinness World Record (which they're looking set to break this year) in sight, but Jase says: "I remember this year just being a little bored and a little A.D.D and saying to PJ, 'let's up it'."

At first, PJ thought the whole thing was a "stupid stunt" but it turned out to be a lot of fun, and "one of the most rewarding moments I've ever had in radio...it challenges you".

There's been flamingos, puppies, streaking, dancing, arguments with spouses, and just general nonsense, and now they're so tired they're not even feeling tired anymore.

They did have a bit of a "make or break moment" in the wee hours of Friday morning in which PJ was crying for no reason and Jase had the shakes and was "a little bit delusional".

But they've pulled through and they're ready to knock out the last few hours before recovering over the weekend.

Here's some of the best stuff that's gone down since starting on Wednesday.

The time they called the one person who might understand:

It was 11:30pm and Jeremy Wells was having his own troubles, as he was in the middle of Hauraki's "No Sleep 'Til Breakfast", in which he and the Hauraki team stayed up for 24 hours broadcasting in Christchurch.

He ranted about cake, "what a city" Christchurch is, and rubbing his phone on his body. Because sleep deprivation.

The time Jase started dancing

And this was fairly early on, too.

We tried to get Jase to dance... Wow.

The time PJ got hypnotised - or at least tried

At least she was a good sport about it.

Hypnotising PJ didn't go so well this afternoon #52Hours

The time PJ went streaking

This was around the halfway point and the team at The Hits weren't even mildly surprised.

Sleep deprivation causes you to do crazy things... like streaking through The Hit's radio studio....

The time the treat door really delivered

When Jase and PJ open the treat door, there's usually something in there that aims to keep them entertained and awake.

Except when there's a naked man instead.

The time they finally broke down

And PJ nearly cried when Jase suggested they aim for 53 hours next year.

There ain't nothing like a 4am breakdown...

And of course, The Rodmance

The formula's simple. Basically you take a single lad (Rod) from the studio and invite listeners to come in and pash him at 1 o'clock in the morning.

Because when you haven't slept in days, everything's a good idea.

And the best part is, even after days without sleep the pair aren't ruling out upping the stakes again and going for 53 hours next year.
