sasseez: always thought that was cool... good song and funny clip
If you know the story behind it it's even funnier.
Paul Simon is rather well known. He went to a party in New York and the host greeted him as Al and called his then wife Betty. Whenever he saw them in the evening he would still call him Al and his wife Betty. Paul Simon and his then wife (can't remember her name) kept on wife the Betty and Al six weeks after the party. An that's how a song was born. With the clip of Chevy Chase it makes it too funny.
