I'd become the supervillain Mr. Car Pooer On While Being Invisible. I would be invisible at the time so nobody could assume that I was pooing on cars. When I poo on the cars, I would wipe the whole windshield with my fecal matter and then run off with my trousers left at the scene - my signature move, that. You cannot steal it. I've patented it, dickhead.
I'll poo on loads of cars within the month, and then the next month I'd take a holiday because everyone needs a holiday, even supervillains who fight society by pooing on cars while being invisible. I'd like to go back to Cuba and Greece - that'd be nice. I'll probably take some photos with my digital camera and make a scrapbook of holiday fun showing myself enjoying my time there. Wait. That's a flawed plan. I'm invisible. well, still, I can take photos of the scenery so I can enjoy it later.
When I come back from holiday, I'll take a big poo on a Bentley or Hummer. I don't like them cars.
