Well, after a long time, a friend just sent me a nice riddle.
I didn't solve it yet, I just got it...
There are 7 men and each man has a dog. they're all on the same island and need to get to the other island. There is one boat which can hold up to 3 beings. Every man knows how to sail, but only one dog knows. The dogs between themselves get along just fine. But, if a dog is left with men, and without his own master, he will go wild and eat them!
How do you cross all the men and dogs to the other island?
