Whether we like it or not, our moms shape who we are, and influence how we feel about so much in our lives. This episode is devoted to the music that is embedded in our DNA, thanks to our mothers, or in Holly's case, for her children. Dave goes to showtunes, movie musicals, and one-hit wonders from the 60s and 70s. Holly's mom is all Classic Rock and 90s Alternative. It's an emotional episode filled with bad singing, dancing, and Seinfeld clips. Happy Mother's Day!
