There are few people better at improv than the great Kristen Wiig. The Ghostbusters star appeared on The Tonight Show Starring Jimmy Fallon dressed in an elegant gown and posed as JoJo Fletcher, the current Bachelorette. Wiig (as JoJo) and Jimmy Fallon discussed this season of the show, which Wiig definitely, definitely watches. They even did an improv duet together. And the best part was watching them both try and keep from laughing through the whole skit. Brilliant.
