I thought that this might come in handy. Below is just about every bit of dialogue that comes out of an Autobot's mouth in Transformers: Revenge of the Fallen. I say "just about" because there are parts where Skids and Mudflap are bickering over each other and making it impossible to discern what they're saying. However, any bickering remarks that are audible are listed. Also, it was difficult to figure out which of the Twins said what while in their ice cream truck vehicle mode, so I tried my best and attributed dialogue to either two based on my familiarity with their voices. There are also some places where what Jetfire is saying is indiscernable, and those places have been marked as such. If anybody knows what Jetfire is saying in these places, feel free to fill me in. Wheelie's dialogue is not included because I don't consider him a true, blue Autobot (even though he is blue). Bumblebee's listed dialogue consists of any audible words that came from him (song lyrics, voice clips, etc.). Jetfire, by far, has the most dialogue out of any of the Autobots. After Jetfire is Optimus, and after Optimus are Skids and Mudflap, who are pretty even. Jolt is last, obviously. Quotations are separated by either considerable periods of time between said quotations or if another character begins to speak.
