Biz and Theresa talk about teething and back up the discussion with so many scientific facts that we consider having the show recategorized from comedy to science. (Note: "facts" stated by Biz and Theresa may not be true / may make you less smart.) Plus, Theresa advises you to never leave before the raffle, and Biz gets weird about a comment on last week’s show. We're joined by singer-songwriter Ellen Harper to talk about the new album Childhood Home, which is a collaboration with her son Ben Harper.
