Joke: accurate but totally useless

A skydiver is blown off-course and lands in a tree in a remote area. After dangling from branches for an hour, he spots a hiker walking by. "Excuse me," yells the parachutist, "but could you tell me where I am?"

The hiker looks up and says, "Yes, you're twenty feet above the ground." "Thank you," replies the skydiver, "You must be an Singaporean."

"What makes you say that?" asked the hiker.

The skydiver answered, "Because what you just told me was 100% accurate, but totally worthless!"
