Earlier this month, a rotten tooth yanked from John Lennon's head sold for $31,200 at auction. Now, an even more boring piece of Lennonalia is on the auction block: a to-do list written in black ink on a yellow legal pad.

"HBO guy coming," Lennon notes. "Would it be a good idea to make sure BOTH CARS have full GAS TANKS?" Bidding starts at $3000. Now if only we could find the list where John Lennon outlines everything he has to do before getting his rotten tooth pulled, we could solve all global economic crises forever.
