Every year on Big Week on the Farm, we watch our favourite celebs take a knee and milk a cow like their lives depend on it.

From Nathan Carter to Aoibhín Garrihy and Alison Spittle to Anna Geary, Ireland's finest entertainers have taken part in the 'Pull the Udder One' competition. It's the stuff of TV legend.

Last night, radio presenter Marty Whelan joined hosts Ella McSweeney and Áine Lawlor for day two of the programme and was roped into competing for the golden udder (yes, it is very much a real thing).

From the get-go, Marty had issues getting to grips with his chosen cow; Milk spurted into his eye and he was pretty convinced that Dubliners were being conned into doing the farm work for free.

"I think this is great that you have people coming down from Dublin to milk your cows. Would you not get a machine like everybody else," he joked.

To find out how Marty ranked in the Pull the Udder One leaderboard, watch the clip above! 

Now that you know what it's all about, why not watch Nathan Carter go on the pull?

Or watch Aoibhín Garrihy moove up the leaderboard...
