A fan of Hamish and Andy's podcast has been hailed a genius after he demonstrated a very special skill to the comedians.

Elliot, 18, wrote into the show and told the broadcasters about his bizarre special skill where he "can perfectly draw a line on a piece of paper to a desired length without using a ruler," the teenager wrote.

"Or can perfectly identify the length of a line drawn on a piece of paper to the millimetre. You can choose which is better."

He has since been dubbed the "line length expert".

Hamish and Andy invited Elliot into their podcast studio to put his special skill to the test and he didn't disappoint.

For his first challenge, Hamish drew a line on a piece of paper and Elliot had to determine its length with a one millimetre margin of error.

"Lock in, maybe 8.4cm," Elliot said after staring at the line for a few seconds.

"It's 8.3cm!" a stunned Andy revealed.

The hosts then challenged Elliot to draw a 4.8cm long line.

When he was done, Hamish grabbed a ruler and said in disbelief: "Are you kidding me? It's the skinny side of 4.9cm. He's got it!"

Elliot narrowly missed out on successfully completing the third challenge from Hamish and Andy which you can watch in the video below.

But they were extremely impressed by Elliot's talent.

"That was one of the most incredible skills we've had on the show," Hamish told him.

Fans of Hamish and Andy's podcast were impressed too, with one writing on Facebook: "Me before this started: 'This is the stupidest special skill ever.' Me during and after the segment: 'This is the greatest thing in the world!! The kid's a genius!!'"

"Truly a god amongst men," commented another fan.
