Someone seems to be just a tiny bit touchy these days. Perhaps Howie is worried that his own pomposity will be less laughable after Colbert leaves?
I guess Howie didn't care for Colbert's skewering of his idiotic claim that Ferguson wouldn't have been a big deal if the media hadn't been there. In response to Colbert, Howie said, "I hope you will be safe when you have to get in front of the camera at The Late Show and survive as yourself after dropping your protective cloak as a pompous blowhard."
Oh, Howie. You're one blowhard short of a sense of humor.
