This week, the Democratic National Convention included many famous and powerful speakers, including President Barack Obama, former president Bill Clinton, and their omniscient puppet master, actress Meryl Streep. It also, for some reason, featured f*cking a cappella, something that's barely tolerable when 18-year-old girls who aren't good-looking enough to join a sorority do it, let alone famous Hollywood people. Luckily, John Oliver stopped by The Late Show with Stephen Colbert last night to help his old Daily Show friend out with an updated version of the DNC's "Fight Song."
