Happy Birthday, Baby

Emily and Richard rejoice when Rory announces her decision to attend Yale; Kirk sustains baking-related injuries when Rory secretly enlists the help of her fellow Stars Hollows citizens to bake the world's largest pizza for her mother's birthday party; Michel and Tobin compete over giving Lorelai the best present, but Richard wins the contest hands-down with a check for $75,000 that's actually the proceeds from an investment he made in Lorelai's name at her birth; Luke confronts Jess about skipping school to work at Wal-Mart, but is blown off as usual; when Lorelai decides to use the money to pay back her parents for Rory's Chilton tuition, Emily becomes furious with Richard for giving Lorelai the money, fearing that the repayment of their loan is a sign that she'll never see either Lorelai or Rory again; Luke makes a bad impression on Nicole's parents, scaring them off with a rant on the horrors of parenting Jess.
