Oblique work outs for men?!

I've tried different exercises for my obliques but I'm just not feeling it. I want something to wish I will feel a burn after I'm done. The more exercises that you can give me the better; it will let me change to different things from time to time and not have my muscle get used to them and minimize muscle growth.

this is a link of what i'm talking about (i'm shirtless so don't get all surprised >_<)

please try to include a link or something that shows and explains hot to properly do the exercise. Thanks in advance.
