The vote for class president parodies the 2000 US presidential election between George W. Bush and Al Gore. Notable similarities include the inconclusive results, endless demands for recounts, the "absentee voters", controversy concerning unclear voting ballots, alleged nepotism by a candidate's family member (in that case George Bush's brother Jeb Bush), and the ensuing legal action through lawyers. The indecisive student with the deciding vote is named Flora, a reference to Florida having the decisive electoral votes but being too close to call for several weeks.
