Superbowl Commercials 2010 - Taco Bell and… Charles Barkely?

As a Canadian we get tortured with bad ad after bad ad.  Thanks to the internet I get a chance to take it all in.  So far not good though.

Taco Bell “It Rocks, It Rocks” (…no it doesn’t)

I’m assuming this is to pay off Charles Barkely’s gambling debts..?  What was Taco Bell thinking?  Moreover, how does this sell product?
