Taskmaster has proven to be a cult hit since it arrived on our screens in 2015.

In a nutshell, five comedians must complete outrageous problem solving tasks in order to be awarded points by the Taskmaster and his assistant. 

Its seamless blending of comedy and problem-solving has seen the once Edinburgh Fringe segment become an internationally acclaimed show.

Taskmaster now spans across five seasons, with an American version fronted by Reggie Watts in the pipeline.

We've pulled together five reasons why you should give it a go, y'know, just in case the above blurb hasn't convinced you already.

1. The Taskmaster:

Famously Mr Gilbert in the Inbetweeners, British stand-up comic Greg Davies is the Taskmaster.

As Taskmaster, Greg is the judge and jury. He watches the contestants carry out the tasks and award points based on their performance.

He likes to come across cruel and unforgiving, but really Greg just enjoys messing with them.

He's devilishly funny, and his bromance with his assistant Alex Horne (of the Horne Section) provides some top quality banter.

2. The Comedians:

No panel of contestants is the same.

Mainly comprised of famous comedians from the UK, and Richard Osman, the contestants stamp their own unique brands of humour on the show with their different ways of approaching the tasks. 

Each season sees a new set of five contestants step up to the plate:

Season One:

The OG contestants on Taskmaster were: Frank Skinner, Josh Widdicombe, Roisin Conaty, Romesh Ranganathan and Tim Key.

Season Two:

Season two proved the show wasn't just a one trick pony. This season's hilarious panel was made up of Doc Brown, Joe Wilkinson, Jon Richardson, Katherine Ryan and Richard Osman (who was frequently reminded that he isn't in fact a comedian).

Season Three:

Taskmaster's third season saw Al Murray, Dave Gorman, Paul Chowdry, Rob Beckett and Sara Pascoe take on some of the wildest tasks yet.

Season Four:

Season four is the first season of Taskmaster to be extended from five episodes to eight. This means you'll get even more of contestants Hugh Dennis, Joe Lycett, Lolly Adefope, Mel Giedroyc and Noel Fielding (The Mighty Boosh).

3. The Tasks:

Ever tried smashing back as much watermelon as you can in a minute? 

How about making emptying a bathtub without tipping it or taking out the plug?

The tasks are wacky, wild and wonderful. We wish we could be in the brainstorming session!

What's even better is you get to watch as the contestants struggle through them. It can sometimes be painful to watch, particularly if you know how you'd complete the problem!

Get ready for trying to paint a picture of a horse while on horseback, moving a boulder the furthest distance in an hour and an unhealthy obsession with potato related tasks.

(That's legitimately just scratching the surface).

4. The Rules:

Rule #1: Whatever the Taskmaster says goes.

Rule #2: There really is no other rules.

The rules of the tasks are outlined at the beginning, but they're really up for interpretation. 

Ultimately the final say is with the Taskmaster, and he's open to being convinced by the contestants. Strong reasoning, and bribes have been known to help.

5. There's Heaps of It:

The first three seasons are available in full on TVNZ OnDemand right now.

Season four is currently playing out on Thursday nights at 8.30pm on TVNZ DUKE.
