John Owen Lowe is coming for Rob Lowe‘s thirst traps. During this morning’s episode of The Drew Barrymore Show, John Owen revealed just how “easy” it is to poke fun at his famous dad.

While chatting with the father-son duo — who both star in Netflix‘s new comedy series Unstable — Drew Barrymore brought up John Owen’s tendency to hilariously troll Rob on social media.

“It started technically before social media. I’ve always given him a hard time because it’s very easy to,” he joked. “And then when social media came to be, he continued to be his ridiculous self.”

John Owen looked to his dad and told him, “You make it so, so easy,” before adding, “He posts these lay-ups where it’s like a shirtless selfie in front of his Emmy nominations. I’m like, ‘Why’d you frame it like that, man?’ It’s so obvious.”

While the St. Elmo’s Fire actor said it’s the “wall in the gym,” John Owen — who called BS on Rob’s claims that he “didn’t even know” the Emmys were behind him — replied, “No, there’s four walls. That’s not the only wall.”

That wasn’t the only post Rob got roasted for on the daytime talk show.

John Owen made sure to point out that his dad posts “a lot of thirst traps for a 59-year-old man,” which Rob brushed off, saying, “I don’t even know what a thirst trap is, so that’s impossible.”

Meanwhile, Barrymore said John Owen “couldn’t be more right” as she pulled up a photo of Rob sitting shirtless with his two sons on a boat. She then followed up the picture with John Owen’s edit, in which his father’s face is replaced with John Stamos.

When Barrymore asked, “How did the John Stamos thing start?” Rob revealed, “He does that to our Christmas cards. He won’t stop.”
