Here is the first post on this wonderful thread:
"We are looking for funding to design and build a Revolutionary Lev Train to transport people and cargo without all the hassle of going through the airport, and we're asking you to read the blueprint and decide if you would like to buy shares in this revolutionary new industry.
It's a commonly known fact that a piece of bread with peanut butter will always land face down and that cats always land feet first.
So we plan to harness this power by attaching thousands of cats onto giant slabs of peanut buttered toast and they will then spin inches above the ground never touching it.
We plan then to attach this contraption to the bottom of our vehicle and be able to have cheap quick safe transportation.
If anyone is interested give me money to buy peanut butter, or donate a cat."
