The classic reality show American Chopper has captured social media's attention, and it has nothing to do with its recent reboot.
You may have noticed a series of arguments on sites including Twitter using images featuring the series' two stars: Paul Teutul and son, Paul Teutul, Jr.
It features a panel of five images arranged almost like a comic book, with white boxes where someone could add their own text.
Still confused? Let's break it down:
Where did it originate?
The original argument stems from an episode of American Chopper, where Paul Sr., fires his son. The two fought a lot during the series, and this was among their biggest dust-ups.
According to Know Your Meme, a website breaking down the origins of viral content, the comic strips date back to 2011, through a pair of posts published to Reddit.
When did it become popular?
The resurgence of this American Chopper comic appears to have started around late March, with users including @_ericcurtin quietly bringing it back. As of Friday, that tweet has more than 54,000 likes.
Since then, it has taken over Twitter. Here are a few of the best ones. And you can even make your own.
