Episode 6: The Great Filter! Aliens and the human condition

This week Peter teaches Ivan about the great filter. A theory that tries to explain why we haven't made contact with aliens. We get pretty serious, Peter gets pretty racist, Ivan gets pretty hateful of the human race. Also see if you can spot where Ivan forgets Jeff Goldblum's name.
