Optimus Prime Went on Letterman

…to help promote his scrappy little indie film Transformers: Revenge of the Fallen. Now, although this is technically a Transformers 2 post, I’m going to keep my promise — I offer it to you without judgment on the movie, the Top 10 list itself or even just the general state of David Letterman and late night talk shows. I will point out that Optimus Prime voice actor Peter Cullen clearly is a pretty awesome dude. Thanks to Zortt1 for the tip.
