There's another "bus" one that came through via email a while back. I shall see whether I can find it.

Meanwhile .... back at the Ranch.



Here it is:

You are the bus driver. At your first stop, you pick up 29 people. On your second stop, 18 of those 29 people get off, and at the same time 10 new passengers arrive. At your next stop, 3 of those 10 passengers get off, and 13 new passengers come on. On your fourth stop 4 of the remaining 10 passengers get off, 6 of those new 13 passengers get off as well, then 17 new passengers get on. What is the color of the bus driver’s eyes?

The answer is correct but your presentation does not explain it.

The correct and simpler explanation is:

Yes if Anne unmarried; Jack looking at Anne
Yes if Anne married; Anne is looking at George.

So the answer is independent of Anne's marital state.

Please advise when my million dollar prize is ready for collection.
