Remove In Post Ads from Appearing On One Blog Post?

Hi all,

Looking for advice for the easiest way to remove In Post Ads from only one post on our site. We are advertising a contest we're having across all of our posts, but we're writing up a contest description post and don't want the regular In Post Ads to appear in it.

Is there a quick function I can add to my theme's functions file to remove the In Post Ads from one post on our site? If so, any pointers to how that code would look?
