Follow a random person in a crowded area and put a light towards him while camouflage the saucer. Pretend to be a god and choose that random person as a choosen hero to save the world. Watch as he makes a fool out of himself for 3 days, pretending he was actually a real one. Then, tell the world that i'm actually just an alien and made up a ritual to fool some random person for my ceremonial trial on pranking a random earthling. Then, watch as he gets attacked by a random mob while stealing sht from some research facility and focus on bioengineering dog-eared girls.
I'll took a selfie with Curiosity. I'll took a selfie with Yutu. I'll took a selfie with the Starman. I'll took a selfie with Huygens. Then upload it to the Internet via numerous tor and proxies/
I'm going to sell it to buy a Gundam. On a local newspaper maybe. A nice 60's era flying saucer, used, AC still work, has loud speakers and nice lights. I think I can get a decent amount from it to buy myself a used gundam from Amazon.
What you need are a horde of little miniature saucer drones... Ring, ring! Guy: Who...oh, Amazon... Saucer: Attention humans: I am Cryptosporidium of the planet Furon. This planet is now a territory of the Furon Empire. Resist THIS. Guy: What...NO! -later- Guy: Obviously this calls for a REALLY bad review...
