Vakkotaur

During the trip from Indianapolis to Chattanooga there came a point where the kids were telling knock knock jokes. This went on for a while. After the repetitious banana joke which finally ends with orange, it was getting rather tiresome. The result was the following:

<Kid> Knock knock.
<vakkotaur> Tetra-ethyl lead.
