Sir David Jason's Touring Toolshed co-star Jay Blades fell victim to merciless teasing from the Only Fools and Horses legend in the third episode of their BBC series.
So much so, The Repair Shop star feigned such anger that he ended up storming off-camera after coming under fire from a troublemaking Jason.
The episode, which airs tonight but is currently available online, sees Jason and Blades head to Scotland for the instalment of their all-new hobbyist show.
David & Jay's Touring Toolshed has already been lauded by viewers after the first two episodes followed the duo to the Midlands Air Festival and the Kelsall Steam Festival in Cheshire.
Jason, who only recovered from a hip operation late last year, accompanied Blades to Scotland for the third instalment and among their adventures, they got to hear from professional barrel maker Craig about the art.
After Blades was put through a "crash course" on barrel-making, he decided to give it a go - although rather than a supportive voice from nearby, Jason spotted the opportunity to tease Blades over his barrel-crafting attempts.

"Just remember we haven't got three days for this programme..." Jason quickly teased as Blades tried to get to grips with the assembly.
"It's gonna fall in," Jason continued to tease to which Blades hit back: "No, it's not gonna fall in! Listen, less of the verbal over there, alright?"
But Jason's critiques kept on coming: "You should've been way down with your rings on the barrel by this time."
When Craig lent a helping hand, Jason didn't let up as he quipped: "Oh, you're having the help from the professional."

Timing Blades, Jason relished putting the pressure on his co-host as he insisted he only had 10 minutes to complete the barrel.
After describing Blades' creation as wobbly, it was Jason who had grown impatient as he told Blades: "Go on, lift it up!"
"Oi," Blades hit back as he stopped what he was doing before Jason suggested using his thumb to help keep the structure sturdy.
But Blades cheekily clapped back at the Only Fools star: "I'll tell you where I'll put my thumb in a minute if you don't stop talking."

Jason chuckled but wasn't going to relent teasing his co-star as he continued to time him and when Blades decided it was time to flip the barrel over, the 83-year-old mocked: "Look out, it's gonna fall to bits now!"
"You need to do one you do," a frustrated Blades replied but Jason continued his onslaught after spotting a gap in the barrel.

Touring Toolshed walk off: Sir David Jason relished teasing Jay Blades

"The leaky Jay barrel," Jason quipped before expert Craig marked Blades' attempt as a four out of 10.
Blades then whipped off his apron and feigned he'd had enough of the pair's brutal swipes at his creation.
"The two of you can do one, I've had enough. I've had enough," Blades told the duo before storming off-camera and away from the barrel-making area.
With Blades out of earshot, Jason conceded: "To be honest, he didn't do too bad, did he?"
The Only Fools star then joked he and Craig could head off and drink whiskey after Blades had left.
