getting abs

What are some good ways to get a six pack of abs (not beer) fast?

yeah jogging/running works good. pushups/pullups will also give you better abs as well as bigger back/chest muscles. crunches are good too. i remember also this one exercice where you have to lay on your elbows:

        o______
       _/     [x] <- chair or bed or something.
just stay in that position for as long as you can. will train your abs + lower back muscles.
also the best way to have visible abs/six pack is to lose weight. you can have good abs but if there's a layer of fat covering them, nobody will ever see them.
