Stop reading if you've already heard these, but I found this Harper's-style list of Palin/McCain zingers at a random political listserv on Yahoo!:
45: number of months Sarah Palin has been pregnant
20: number of months Sarah Palin has been governor
9,000: population of Wasilla, AK the town of which Palin was mayor 15,000: the number of people at the rally announcing her nomination as VP
7: number of people in the Palin family
7: number of houses John and Cindy McCain own
72: years that John McCain has been alive
49: years that Alaska has been a state
1: number of times McCain and Palin had met before today
20 million: the number of dollars that the city of Wasilla was left in
debt when Palin's term as mayor ended
When John McCain started his campaign, Sarah Palin was not yet governor of Alaska.
John McCain left both his first wife and Mitt Romney for beauty queens.
A mystery grand prize goes to the commenter who writes the best addition to the list.
