Greetings humans. It's me, Megatron. I don't know if you saw this at the time because it happened in 2009, but I bet you've heard of the LATE SHOW WITH DAVID LETTERMAN. But get this: that stupid arch enemy of mine, Optimus Prime, appeared as a guest. LOOK! David Letterman-Top Ten Optimus Prime Transformers - YouTube I AM SO JEALOUS! Maybe I should do something just as interesting, like get an interview with Ellen Degeneres on Ellen. Discuss this video.
