He was preparing to appear on the news by bossing crew members around when Yakko, Wakko, and Dot appeared bringing in his lunch (which he ordered hours ago). Slam was about to eat his sandwich, but Dot swiped it and took a big bite out of it. The Warners expected to be paid $18.15, but Dan refused to pay, since he didn't even get his sandwich.
After Anchorman kicked the Warners out, they began exacting their revenge by saying mean things about him, giving him makeup that makes him look like a clown (this scene was removed from reruns), playing with the special effects, and changing channels that make him appear on different shows and films (such as "Gilligan's Island, "Godzilla", and even a WWF match. In addition, there was a bit featuring a cameo by Slappy Squirrel which was also cut for violence.)
Because of this torment, Dan went completely insane, and as reported by the Warners, he was taken to a mental hospital for a nice, long rest. The Warners ended the news broadcast with this tip - "Be real nice to people who handle your food, or else it's sad news."
