"George Bush taking credit for the wall coming down is like the rooster taking credit for the sun rising"

This quote by Al Gore is a funny method of criticizing former President George Bush for taking credit for the fall of the Berlin Wall. The Berlin Wall was a sign of the Cold War and its fall in 1989 marked completion of the Cold War. Al Gore is indicating that George Bush had absolutely nothing to do with the fall of the wall and is rather comparing him to a rooster taking credit for the sun increasing. This contrast is implied to show how outrageous it is for George Bush to take credit for something he had no part in. Al Gore is highlighting the absurdity of George Bush's claims and stressing that the fall of the Berlin Wall was an outcome of the cumulative efforts of lots of people, not just one person.
