What are good exercises for better abs?

Does anyone know any exercises to get better abs. It doesn't matter if they are quick or simple or whatever just if they can get my stomach in better shape. Thank You

Well, I do sets of 10's where you do 10 sit-ups, 10 leg-raises, 10 pike-ups (its sit-ups and leg raises combined) and then 10 rocks (place your hands beneath your lower back and rock back and forth but don't let your head or feet ever touch the ground!) Do it all in a row and non-stop at least once every night, and it works really well! Feel free to fun mail me if you have anymore questions!

Probably the best ab working exercise is the flutter kick. Man do my abs burn after those.

Planks work really well when shaping your abs,
