Russell was recording an interview with the station's Ron Bennington, in which he put forth his ideas for a modern society and said "altruism, meditation, reflection and transcendence" will save us from a "sugarcoated culture" in which we're eating bad food and "listening to bad ideas all the time."

"It's not like he's a person who's a super guy or anything. He's just good at hungry hippo, and we live in hungry hippo land."
