"Quel Malentendu!"

- Ernest when he misunderstands someone

"They laughed at us, but now it's our turn to laugh back. Embrace your inner lemon. Let it drive you. This was meant to be alternate fuel's greatest moment. After today, everyone will race back to gasoline and we, the owners of the largest untapped oil reserve, will become the most powerful cars in the world! They'll come to us and they'll have no choice, because they will need us. And, they will finally respect us. So, hold your hoods high. After today, you will never be ashamed of who you are. Long live lemons!"

- Sir Ernest of the Cross rising to power on the monitors.
