This is a recut version. NBCU blocked the Leno clip. The storyline is now punctured, but what can you expect from a network with Jimmy Fallon as the Tonight Show host?

1. February 7, 2010. CBS airs the ad.
2. February 12, 2010. Oprah Winfrey talks about the ad.
3. February 8, 2010. Dave talks about the ad.
4. February 8, 2010. Jay talks about the ad. - BLOCKED BY THE BIRD NETWORK
5. March 24, 2010. Dave talks more about the ad.

I extracted the Oprah clip from another You Tube channel years ago. It doesn't appear to be available anymore, but if anyone can find it, I'll credit the uploader and provide the link.

As others have pointed out, Dave is wearing Art Donovan's football jersey number. Art would pass away three years later.
