Verizon IndyCar Series driver Graham Rahal visited his famous godfather, animal expert "Jungle" Jack Hanna, at the Columbus Zoo for a behind-the-scenes tour ahead of this week's Honda Indy 200 at nearby Mid-Ohio Sports Car Course.

The Rahal Letterman Lanigan Racing driver stopped by his hometown zoo to see the noted zookeeper, who is also credited for putting Graham's father, Bobby, in contact with late-night talk-show icon David Letterman. It resulted in Letterman becoming a co-owner of the team for which Graham drives. Watch as Graham and Hanna discuss that and more, and they interact with some of the animals at the zoo's exhibits.
