Matt Damon is starring in the family movie We Bought a Zoo, but did you know he also voices the animals in the film? Well David Letterman got his hands on the video showing it and aired it on The Late Show. I wonder how Matt got so good at doing animal impressions? Is that what he sounds like in bed? Actually I don’t want to know because can you imagine hearing his seal impression when you are in the throws of it? Talk about a moment killer.
