Toyota Enlists James Lipton to Help Determine Plural of Prius

In their continuous search for the plural of Prius, Toyota has turned to James Lipton who, in a new video, interviews William Shakespeare, an octopus, a rapper, and others to get a handle on the proper word for the plural of Prius. Shakespeare think the correct word in Prium but his suggestion falls to the bottom of the list. Here are the current standings:

Prii: 25%
Prius: 24%
Priuses: 20%
Prien: 19%
Prium: 12%

Saatchi & Saatchi is the agency behind the work which also includes a Facebook page on which people can suggest and vote of potential candidates for the word.
