LONDON, ON—According to eyewitness accounts, local uncle Bob Nelson is busy putting the finishing touches on a long and rambling Thanksgiving blessing, in which he reportedly plans to repeat the phrase "All Lives Matter" at least seven times.

Nelson's pre-meal prayer, which will also touch on such subjects as "the so-called media" and "that vehicle registration tax," should last roughly 11 minutes, breaking his own endurance record set last year when he railed against "that Justin Trudeau."

"I've never seen anything like it," says nephew Ryan Poole, who overheard his uncle running through a draft of the blessing this morning. "He wasn't even trying to connect the idea of 'All Lives Matter' to any particular context. By the end he was just throwing it in as verbal filler."

"A few times, he even said 'pound sign' before repeating it," adds Poole. "I'm pretty sure Uncle Bob meant to say 'hashtag'. Not that it would have made it any less weird."

While Nelson has led the family's Thanksgiving blessing every year since his father Walter's passing in 2005, his relatives suggest that his speeches only began to veer into bizarre diatribes and right-wing talking points sometime around 2011.

"That's the year Aunt Kathy divorced him," explains niece Margaret Nelson. "Ever since, I don't think he gets out much. In fact, Thanksgiving at Grandma's house might be the only major interaction Uncle Bob has outside of the comment section of YouTube."

In anticipation of their uncle's long-winded rant, the Nelson cousins say they will be making great efforts to mitigate his contrarianism for the rest of the meal.

"This morning we got an e-mail thread going to list all the stuff we shouldn't bring up in Bob's presence," says nephew Eric Nelson. "So we're prepared."

The list, which includes such diverse topics as rapper Kanye West and their respective arts majors, should help prevent their uncle from engaging them in near-constant unwanted debate.

"We're going to do our best to stay on boring subjects like the weather," says Poole. "That said, Uncle Bob firmly believes global warming is a hoax."

"The blessing really gets Uncle Bob in the zone," he adds. "Maybe it's foolish to think we can neutralize him."

When reached for comment, Uncle Bob said he "loves to spend time with his family and had a great time last Christmas," which was when spent several hours denouncing the "War on Christmas."
