WATCH: Fox News Reporter Flees When Interview Goes Hilariously Wrong

Don't mention the "P" word.

A “Fox & Friends” segment went off the rails early Thursday when a man in a Maryland diner expressed an opinion not heard very often on the network. 

The diner wondered aloud if President Donald Trump’s firing of FBI director James Comey had something to do with the investigation into Russia, and the interviewer then ended the exchange rather quickly.

Griff Jenkins of Fox News was at the Tastee Diner in Bethesda, Maryland, asking the customers what they thought of the president’s decision.

Most agreed Trump had the right to fire Comey, although some said he went about it wrong.

But one diner took things in a different direction while speaking live on Trump’s favorite morning show.  

“I think it should have been done much earlier,” the man, identified as Pat Flaherty, replied. “Not to be too Machiavellian about it, why does it take such a long time for these guys to arrive at this conclusion?”

So far so good. 

But then the diner went off-topic ― at least for Fox News ― and mentioned the “P” word. 

“Is it because we’re getting too tight? Finding out too much information about the Putin?” he asked. 

That got Jenkins to wrap things up very quickly. 

“Well, thank you, we’re getting tight on time,” he said as he left the booth and moved on to another diner. 

Despite being “tight on time,” Jenkins spent about another minute talking to the next diner and showing off a local newspaper before throwing back to the studio.

Several Fox News shows have been reluctant to mention the investigation into alleged links between the Trump campaign and Russia, often dismissing the probe altogether when it’s brought up. 

On Wednesday, Fox News host Sean Hannity called the allegations “completely insane, bizarre conspiracy theories.”
