I downloaded a bunch of episodes of Norm Macdonald Live to listen to on a long drive. This one came out in 2013 - well before the scandal broke. It is probably nothing, and even if it is something, I don't know if there's anything useful to explore.

Around 53:43, they read an audience member's question and they asked Russel "how much do you love white pizza?" He seems super put-off by the question and says he doesn't even know what it means. I distinctly remember thinking that was odd when I originally watched it in 2013, because I assumed they meant pizza with white sauce which I freaking hated (and still do).

Could be just a dumb question from a retarded audience member but it was a pretty weird thing.
