How to get 1 or 2 specific posts on top of my wordpress blog?

Question

Does anyone know how to get 1 or 2 specific posts on top of my wordpress blog all the time? I mean just like in a forum where you can sticky a post so they are always on top of the other posts.

Is this maybe a simple line of code (i am not realy a coder) or does anyone knows a good plugin for this?

Any help would be realy appreciated.
