Piers Morgan and Susanna Reid deal with a huge variety of people every single day when they present Good Morning Britain.
But it's obvious some are more difficult to deal with than others, considering they cover a broad range of people.
Speaking exclusively to Digital Spy, the pair revealed who they found the most challenging to interview.
"Some of the American gun nuts are a big challenge because they are so aggressive and so blindly partisan to what they believe in. It's tricky to take them on," Piers said. "They are very provocative and controversial."
Susanna added: "Sometimes you get a lot of backlash, for example when Steve Bannon was on and when Tommy Robinson's been on. You get quite a lot of blow back from that, but that's just part of the job. You have to roll with it.
"Our job is to interview people in the news, Robinson, Bannon. These people may be polarising or obnoxious to some people but that doesn't mean we shouldn't interview them," Piers continued.
"You have to hold these people to account. Interview them, talk to them, challenge them. It's part of the job."
Digital Spy had an exclusive tour of the new ITV studio, where the channel's daytime TV will be broadcast from for the next four years.
Piers also discussed how long he plans to stay fronting the early morning TV show, hinting it could be very soon.
"Until the end of next year because I am contractually obliged to do it until then," he said.
Susanna added: "Then he's open to negotiations."
Good Morning Britain continues on weekdays from 6am on ITV.
