Alright these are very simple and actually very stupid riddles. But lets see how soon can you crack them.

1. Six glasses are in a row. The first three are full of juice; the second three are empty. By moving only one glass, can you arrange them so empty and full glasses alternate?
2. Two fathers and two sons went duck hunting. Each shot a duck but they shot only three ducks in all. How come?
3. Brothers or sisters have I none, but that mans father is my fathers son. Who is that man?

Go on

2) Those are grandfather, father and son
3) Son

take the juice from the second full glass and pour it into the middle empty one, replace the original glass. They now alternate full/empty with only moving one glass.
