"It's the best stand-up show you'll see in New Zealand this year for the first half, and then it's 7 Days live, unplugged, uncut and uncensored for the second half."
Corbett said they had visited Whanganui previously, a city they love, and there had been many memorable moments.
"When we come to see you guys, we're guaranteed to see a drive-by shouting. We walk down the street in Whanganui and we always have people in cars yelling things at us.
"When we don't come to Whanganui, people are like 'why have you missed us out, why aren't you coming' and then when we do come, they haven't bought enough tickets."
"Tell them to go out and buy some bloody tickets or we'll cross you off the list next year."
• 7 Days Live starts at 7pm on Saturday at the Whanganui Opera House. Tickets from Ticketek.
