Al Gore is a former Vice President of the USA and a published author. He wrote the book Sane Planning, Sensible Tomorrow.
When the Simpson family went to Books! Books! And Additional Books!, Lisa bought two books: a biography of Peter Ueberroth and Al Gore's new book, Sane Planning, Sensible Tomorrow. She said she hoped that Gore's new book was as exciting as his previous one, Rational Thinking, Reasonable Future.
When the bookstore clerk scanned Sane Planning, Sensible Tomorrow at the cash register, a signal traveled to The Pentagon and Gore was notified that someone had finally bought a copy of it. When he got the news, he said, "Well, this calls for a celebration." Gore then put on an LP record and played the song "Celebration" by Kool & the Gang. When the song got to the lyric, "Celebrate good times", Gore even-tonedly said, "I will."
Martin bought a talking Al Gore doll, spending his last $10 on it. When he pulled the doll's string, it said, "You are hearing me talk."
Al Gore has visited Springfield at least one time, as he was once seen at Moe's Tavern wearing his Nobel Peace Prize medal.
Homer once refused to pay the heating bill because he believed that global warming would fix it, and when it was still cold in the house he yelled at Al Gore. When Lisa was working as Krusty's assistant, he had her edit his joke file, changing every Sophia Loren reference to Lindsay Lohan. Lisa asked if it was a global change, and Krusty sarcastically replied, "Who am I, Al Gore? Just do it."
In a dream Homer had, he met Lara Croft. They talked a while before a giant Al Gore took care of him. Croft told him that he is master of his own fate. Al Gore asked Homer if he knew that the carbon-emitting choice of cars is dooming the planet and it's because of him and his wasteful ways, and that they only have five more years before they fry in a global inferno. He then ate Homer, and when he got into Gore's mouth he woke up.
Al Gore is one of the many people on "Ned's List of Laudable Lefties".
