What? The earth is flat? Then I’m a balloon.
No, you want proof?
You bet your flat feet.
I gotta warn you, parties will try to bamboozle you.
Try me.
Take a long walk with a glass of water in you hand. If it spills, the earth is round.
After.
Well, I  took a long walk, got thirsty and started seeing things, so drank a bit, and the water spilled over.
See, parties put substances in the water.
Try me again.
Take a plane and if you end up topsy-turvy, it’s round.
After.
Well, we ended topsy-turvy alright, cause the pilot started doing somersaults.
See, parties manipulated your perception.
Try me again.
Go find the largest telescope there is, look through it and if you don’t see a sign saying THE END OF THE WORLD, it’s round.
After.
Well, I saw a sign, but it said NO TRESPASSING.
Yeah, parties pretend to have secret military bases.
Heard talk about that, where they keep guys from other planets and their real flat flying things.
