A xacha engineer is walking along when a fellow engineer arrives on a new ryunaak. Impressed, he asks, "Where did you got this beautiful ryunaak?"
"Well," the second engineer says, "A couple of days ago I was just walking along when this gorgeous blonde ylian pulls up, hops off the ryunaak, rips off all her clothes, and says 'take what you want'."
The other engineer nods and says "Good choice. The clothes probably wouldn't have fit."
A diaboli is flying a hot air balloon and realizes he is lost. He reduces height and spots a xachan down below. He lowers the balloon further and shouts, "Excuse me. Can you help me? I promised my friend I would meet him half an hour ago, but I don't know where I am."
The xacha below says, "Yes, You are in a hot air balloon, hovering approximately 30 feet above this field. You are between 40 and 42 degrees N. Latitude, and between 58 and 60 degrees W. longitude".
"You must be a typical xacha scientist" says the balloonist.
"I am," replies the man. "How did you know?"
"Well," says the balloonist, "everything you have told me is technically correct, but I have no idea what to make of your information, and the fact is I am still lost."
The man below says, "You must be a typical diaboli."
"I am," replies the balloonist, "but how did you know?"
"Well," says the man below, "you don't know where you are, or where you are going, You have made a promise which you have no idea how to keep, and you expect me to solve your problem. The fact is you are in exactly the same position you were in before we met, but now it is somehow my fault."
