Play of the Day: Trump and Clinton Prep for the Debate

A new study was published this month indicating that dogs undersand human language in ways previously not known. Late Night's Seth Meyers joked about the study, saying Hillary Clinton's dog Tally knows too much.

The first general election debate will be held next month at New York's Hofstra University and the candidates are preparing for it. Donald Trump may not hold any mock debates to prepare because, as The Tonight Show's Jimmy Fallon noted, Trump will do all his mocking at the debate. Conan O'Brien noted that Clinton has trouble finding a person to play Trump in her preparation debates, but he has a suggestion: A rotting pumpkin with a car alarm in it.
