My book’s on eBay. Don’t tell my mom: she’s already bought three of them through eBay. “Mom, don’t you think they’ll recognize that we have the same last name?” I asked her.
“I don’t care,” she said. “I got it for ten dollars!” On another one she bid until the auction price was thirteen, and then left the bid. Which means she made someone pay more for it than the actual price. [thanks, Andrea, for the link]
