Dr. Dianne Strize (b. 1962) is one of the most famous psychologists in the world and hosts the 'Helpful Hour' on PBS Radio with her partner Phillip (see Episode 13). Dr. Dianne seems to be fixated on babies, describing her parents - who had her young - as babies themselves when they became parents. Consequently she wrote the book 'I Was a Baby' which she occasionally sends to listeners to her show, including Andrew from Cumbin Downs.
Dianne was also a contestant on the Grub Tank (Episode 86) where she pitched her ‘Psychology Sack’, a sack complete with mouth and eye holes, that changes colour based on the mood of the wearer. Ben and Greg both bid to be investors in the idea, thinking that pseudo-science is often profitable, but neither won the rights as the sketch ended in Dr. Dianne sucking them both off. Phillip's thoughts on this development are unknown.
