What's prompted the funnyman tag is Farrell's latest video post on Facebook where he talks about, well, lettuce.

More specifically, his horror at the thought lettuce has a heartbeat.

"I just got off the phone ... and this sheila said to me she didn't like the last post I did on Facebook because lettuces have got a heartbeat," he says.

There's a pause before Farrell repeats: "Lettuce has a heartbeat."

"Some people have just got no bloody idea ... none," he says in disbelief.

In the April 8 post, Farrell remarks that vegans are "going bananas" with blockades, abattoirs chained up and "people locking themselves here, there and everywhere".

An incredulous hay runner said he was "gobsmacked" by the "bullsh**" coming out of people's mouths and couldn't resist a few digs of his own:

"I'm out feeding my cows this morning and I tell you what, there is a steer here that's going to be mm mm mmm, bloody delicious at Christmas time ... I can't wait to hook into it.

"(The) next door neighbour's running lamb at the moment, betcha he's licking his chops at Christmas time ...

"Fair dinkum!"

His tongue-in-cheek rant attracted a feast of Facebook likes and nearly 3000 comments, many in a similar, humorous vein.

"I am concerned at the number of people who torture onions by skinning them alive. Enough to make a grown man cry," one follow quipped.

Another wrote: "Make sure you have some lettuce on your steak sandwich. Cause 2 hearts beat stronger than one."

In a previous post on the actions of animal activists, Farrell was much more serious on the subject, reminding his fellow Australians farmers "are having enough of a battle as it is at the moment".

"Grain and hay prices are through the roof, there's no water," he says.

"These activists don't do anything except destroy lives, it's as simple as that."

Another supporter suggested "every kid should have to do an exchange 6 months in the bush on a farm to reconnect to real work".

"Then they might have a brain cell that can see where their food comes from," they added.

Farrell questioned the point of waltzing into "some poor bastard's property, videotaping whatever they want and destroying his life for the next three to five months".

Instead he urged activists to go about things "the right way" or promote themselves by heading to an outback station or town and offering to help farmers feed their cattle or stock.

Better still, he said, join him on a hay run and do something productive with your lives.

Lettuce has a heartbeat.

It's definitely food for thought.
