Quest for the Lost Ark (Sunday, 8:00 p.m., History Channel) Tudor Parfitt looks more like Jeremy Clarkson than Harrison Ford, but he is a real life Indiana Jones. This History Channel documentary special traces his search for the Ark of the Covenant – the same thing the fictional Indy searched for in Raiders of the Lost Ark.

Also of note this Weekend:
George Carlin: It's Bad for Ya (Saturday, 10:00 p.m., HBO) It is hard to believe that George Carlin is now a septuagenarian. This new HBO special. Safe money says he’ll use all of the seven dirty words he made infamous.

Oprah’s Big Give (Sunday, 9:00 p.m., WABC 7) It is Oprah’s fakeality show. You have been warned.

Unhitched (Sunday, 9:30 p.m., WNYW 5) Yet another sitcom about singles living in a city, but this new Fox series is from the Farrelly brothers, so it will definitely be raunchy (can you say rape by chimp?) and maybe even good even if you didn’t get free hot dogs. Another plus: Rashida Jones is in it!
