I'd get a bunch of those stupid, cheapo plastic bobbleheads and use some of my six hours every day to break into people's homes and place them around their living space.

Then I'd enjoy the news reports on the mystifying 'bobblehead epidemic' that's spreading.

Then one day I'd go to the main square and just use a ton of bobbleheads to spell out something like 'WE'RE ALIENS AND WE'RE COMMUNICATING WITH YOU THROUGH BOBBLEHEADS".

And there'd be no other rational explanation so people would have no choice but to believe it.

And maybe the government would like erect a barricade around my bobblehead message and get special forces to secure the premises and it would be so fucking funny because it's just bobbleheads.
