General Motors has made a lot of dumb decisions in their day, and three-quarters of them are still being sold to gullible car-buyers across the globe.

However, one of their biggest, boneheaded moves doesn't involve a car at all. The soon-to-be-former car manufacturing giant has announced that it's ending its 22-year run as primary sponsor for PBS filmmaker Ken Burns, and it just might end Burns' career in television as we know it.

GM has agreed to edit a commercial that premiered during the Super Bowl which shows a despondent assembly-line robot contemplating suicide. Earlier this week, GM had said it would not remove the ad, despite complaints from a national suicide prevention group.

The commercial features a robot that drops a screw. Because of GM's high quality controls, it's forced to leave the plant, take up several other part time jobs, and finally it jumps off a bridge, only to wake up in the plant and reveal that the whole thing was a dream sequence.

General Motors swears it's just a case of bad timing. The automaker has severed its ties with CBS' Survivor, and the announcement comes on the heels of the controversial news that Survivor teams will be divided by race for the first half of this season. GM says the decision to split with Survivor was made long ago because the people who participate on the show and watch the show don't drive GM vehicles. GM sponsored Survivor for six seasons.
