This week, one of the toughest challenges of Andrew's career: how do you interview a friend of 40 years, someone you've known since you were teenagers, someone you've worked with, laughed with and already shared most of your life with?Andrew and Amanda met at Mitchell College in Bathurst (now Charles Sturt University) when he was 18 and she was 17, both fresh out of high school. They've worked together on TV and radio, and generally been each other's biggest supporters."I immediately knew we were going to be friends," Andrew says of their college introduction, "and we have spent the last 40 years trying to either shock each other or make each other laugh. Often, they've been the same thing."So how do you make an interview like this work? You reach into your loooooong memory list of funny and embarrassing moments and celebrate Amanda, one of Australia's favourite women, by letting her remind us all what a smart, funny and occasionally super daggy human she is.It's the most fun you can have with two people and two chairs.
