I can just picture it "How do we get in on this new "viral" trend?" asks some CEO and sends an unusually gullable exec out to the agency to "come back with some viral ads pronto!".
The following 'viral' film is out of the agency Rethink Vancouver (yes, the people who did that clever 3M poster with money in it), produced by reginaldpike and directed by the Perlorian Brothers. Bless you.
(warning: some may consider this a bit gross.)
