All of my favorites have already been mentioned Top Gear, Kitchen Nightmares, Coupling and No Reservations I'll add Newsnight, also on BBC America. Watch Jeremy Paxman if you want to see a real interviewer, not the non-confrontational kissasses on US news shows.
Chef Ramsay is hilarious. I can't believe no one has taken knocked him out yet. The BBC America version is definitely better. I also like Dinner Impossible.
IFC Shows: -Dinner for Five with Jon Favreau -Minor Accomplishments of Jackie Wilson Canadian Shows -Slings and Arrows -The Industry -The New Red Green Show PBS -American Experience -Frontline -Foreign Exchange w/ Fareed Zakaria -McLaughlin Group ABC -Miss Guided -Notes from the Underbelly -Cashmere Mafia *Also, there's this British mockumentary series called People Like Us, funniest GD thing I've ever seen.
