Letterman Worried That Electric Car Would "Magnetize My Nuts" (VIDEO)

The chairman of Tesla Motors, Elon Musk, went on the Late Show with David Letterman last night to promote the Tesla Model S, another in his company's line very cool-looking, very electric, very expensive cars. The Model S is slated to be sold in two years for around $49,900.

From Tesla's site:

With a range up to 300 miles and 45-minute QuickCharge, the Model S can carry five adults and two children in quiet comfort - and you can charge it from any outlet, without ever stopping for gas.

Dave, an automotive buff, asks great questions even about environmental issues -- like is an electric car really any better if coal is being used to generate some of the electricity?

Here, the car rolls out onto the set and Dave does a really weird thing:
