Well the working Title for episode II literally was Jar Jar's big adventure.
But i'm sure that was Lucas little joke put there for his own enjoyment.
And i really don't think people committed suicide over it.
But then you never know there are nuts out there.
Seriously i saw on the news that in some other country a kid was convinced GTA IV talked to him and told him to go kill a bunch of people. Guess what he went and did kill people.
