A short list. Yours may vary:
Daily reports on Britney Spears
The sports trifecta of steroids, OJ Simpson and Barry Bonds
Two commercials: Fitness Made Simple; Head-On
Your trip to rehab
Celebrities judging talent shows
Tainted things - vegetables, toys, dog food, no-bid government contracts, toothpaste, the US Justice Department, the FCC, open government, all sports, etc, etc
FEMA trailers and fake FEMA news conferences
Scandalous Folk/Behavior: student loans; mortgages; Blackwater; Senators Ted Stevens, Larry Craig, and David Vitter; illegal wiretaps; legislative bills filed by The Rep (aka Stacey Campfield); Scooter Libby
Rationalizing the use of torture
Losing/misplacing government computer database records
Sending me a text message - if you cannot make a phone call or email me, then it really isn't important is it?
People who make insulting/cutesy plays on the words Republican or Democrat.
Those news-crawls or tickers or whatever they are. Pick a news story to report, then report it and go on to the next one. It's not like that 'breaking news' feeling is supposed to be a permanent state of being.
