No. Based on all the Fatman videos and live webcam shows (Unfortunately, I've never gotten him to put a shoe on his head... yet) I've watched, this is how he normally talks. He's also bipolar, which may have a little bit to do with the presentation.
The reason I fived this is because Fatman is right about on the same level of informed-ness and intelligence of 90% of voters of all stripes.
