Try this one

A man rode into town on Friday, stayed for three days and three nights and then rode out, again on Friday. How could this be possible?

You're quick on google Gaz..;)

Try this one.

U2 have a concert that starts in 17 minutes and they must all cross a bridge to get there. All four men begin on the same side of the bridge. You must help them across to the other side. It is night. There is one flashlight.

A maximum of two people can cross at one time. Any party that crosses the bridge, either 1 or 2 people, must have the flashlight with them. The flashlight must be carried back and forth, it cannot be thrown, etc. Each band member walks at a different speed. A pair must walk together at the rate of the slower man's pace:

* Bono: - 1 minute to cross
* Edge: - 2 minutes to cross
* Adam: - 5 minutes to cross
* Larry: - 10 minutes to cross

For example: if Bono and Larry walk across first, 10 minutes have elapsed by the time they get to the other side of the bridge. If Larry then returns with the flashlight, a total of 20 minutes have passed and you have failed the mission.

Yes, but i worked out a cheat to do it shorter.
Thing is..it would make sense, if Bono escorts each person over, seeing as his return journey, would be shorter than anyone elses...but...

Bono and larry cross, bono goes back 11mins
Bono and adam cross, bono goes back
6mins

Thats 17 allready and we still need to bring Edge over...

Unless...once the person in halfway, then bono goes back, with teh torch, to get another.,...assuming once they are on teh brifge, they can make it to teh other side...

That's the way i thought at first, but it does work out. See if you can work out the cheat i thought up as well.
