I only saw the very end but it was a hilarious Nissan Heisman House ad:
Eddie George was driving and they got to a "Michigan" sign so he said "We are going around". The other passengers said "around" then it showed a GPS showing a route East from Toledo, around Lake Erie AND Lake Michigan AND Lake Superior to enter Minnesota from Ontario at Thunder Bay. Then it showed the AWD Nissan turning into a field as the audio was one of the other Heisman winners saying "That's like a 12 hour detour".
