"It's very 'Watergatey,' " [Timothy] Busfield told Distractions from New Jersey, where "Ed" is taped. "I've got this story that I think will become the big story as the season snowballs ... but I haven't told the guys on 'Ed' yet."

Notes from We Hate You (But Please Send Us More Baywatch): The Impact of American Entertainment on the World
Heifers hoofin' it in 'Wing' flingI can't imagine there are many publicity opportunities when you're representing cows - but Heifer International is milking its one shot at glory for all its worth.
Under the announcement, "West Wing Features Heifer International," the group has issued a press release proudly citing the fact that, in tomorrow's episode of "The West Wing" (9 p.m./Ch. 4), entitled "Guns Not Butter," their group is given prominent mention by President Bartlet (Martin Sheen).
In the episode, the president's staff fights a losing battle on a foreign aid vote. "Little Rock's Heifer International gets a prominent mention on the popular series when President Bartlet is asked to pose for a photo with a cow or goat to help publicize the nonprofit world hunger organization," the group notes with pride.
