And if that happens, Corbett wants to know Rotorua residents not to take anything personally and to know the following:
The whole 7 Days crew are very nice, approachable people.
They'll be mortified if they upset anyone.
We want crowd-interaction.
"We're all nice people, just remember that when we start getting stuck into Rotorua," Corbett said. "It's all just entertainment, nothing personal."
Corbett said audience members would get the chance to be involved with the show through the caption competition, the picture game and general interaction.
Rotorua, he says, is "a beautiful place" and the 7 Days crew can't wait to get to the city.
"We want to smell sulphur and we want a hot pool," he said.
The tour starts today in Auckland and will visit Hastings and Palmerston North before Rotorua on Wednesday. The tour will also stop in Timaru, Dunedin, Invercargill, Tauranga, Wellington and Whanganui.
Corbett said touring was always fun but there were times when things could get intense.
"When you get a whole lot of comedians in a van together ... they're all trying to out-funny each other."
Meanwhile, Corbett encouraged Rotorua residents not to wait until the last minute to get their tickets for the show.
He said the 7 Days crew was a good group of people who were funny as an added bonus. And having Ego and Henwood on either side of him was pretty good, too, he reluctantly said.
Though he didn't want to admit it publicly, given Ego and Henwood could find out about it, Corbett described the pair as "brilliant".
Tickets cost $49.50. The Rotorua show will be held at the Civic Theatre and tickets are available through Ticketmaster.
