This is going to sound cheesy, but my favourite part is Pete's voice.
I listen to the podcasts before I go to sleep to clear my head and hearing his voice, EVEN his ranting, sort of puts me at ease. It puts me in a happy "Disney mood" and it's just very comforting to hear his "From the Bawb Varley studio..." that starts off the podcast and ending it with "Stay out of the damn lakes."
Of course, I also love the whole gang's conversations about anything! Like the recent email show and their music choices!
