One of the great things about blogging for mental_floss is meeting people from all over the Web who have pantloads of talent. Some moons ago, I met Greg Tatum, and we brainstormed some animated shorts that would be appropriate for the blog here. I should say, he brainstormed and I nodded in agreement mostly. So welcome to a new mental_floss exclusive animation series: The Adventures of Mr. Rat. Animation: Greg Tatum, Music: Jeremy Engleman
