SALT LAKE CITY — 2017 is coming to an end in the most hilarious way possible.

Three people dressed in T. rex costumes photo-bombed a live MSNBC shot on Thursday afternoon. The costumed dinosaurs are literally fighting in the background as MSNBC host Hallie Jackson discusses the tax law with CNBC’s Ylan Mui.

Neither Jackson nor Mui knew what was going on.

“The anchor and reporter didn't seem to notice the antics in the background, which makes it even better. Nothing but the utmost respect those three brave souls who, intentionally or not, made property tax news a lot more interesting and actually enjoyable for Twitter users all day long,” according to Mashable.

Jackson later responded to the incident in her own tweet.

Jackson talked about the viral moment Friday morning, saying her producers approached the dinos while the broadcasting was happening.

“We’re doing a pretty serious segment,” she said, according to Yahoo News. “(My colleague was) like, ‘Can you please just give us a moment?’ And so the dinosaurs very nicely exited stage left. I don’t know if they’re coming back today."

Social media had a field day with the moment.

Live broadcast interruptions aren't new. Back in March, an expert managed to keep a straight face when his children interrupted his live interview on BBC World News, according to the Deseret News.

While political analyst Robert E. Kelly spoke with the BBC about South Korea President Park Geun-hye's impeachment, his children crept into the background. The children's mother slipped into the broadcast, too, to usher the children away.
