 * Otto takes note of Kang's putting a "Susan B." into the vending machine, referring to a coin.
 * Kodos says that she needs Kang's last quarter for a.

Trivia

 * The vending machine has twenty-one food slots, numbered A1 through G3.
 * The following people are seen in the food slots:
 * Ralph Wiggum in slot G3
 * An unidentified person in slot F3 (immediately above Ralph)
 * Otto in slot B2
 * The machine's selling price for humans is $2.50. Because Otto is aware of this (due to being able to distinguish the sounds of the coins as they're deposited), evidently he has heard at least one person being sold.
