Different Text on Some Category Pages (Codex)

I did something similar. I looped through all of the categories and depending on the category id, I added that category name to a variable which then prints after the loop. You can do something similar.

Here is my code:

$theCatName = "";
foreach((get_the_category()) as $category) {
	if ($category->cat_ID != '36' && $category->cat_ID != 39 && $category->cat_ID != '8') {
        	$theCatName = $theCatName.", ".$category->cat_name;
	}
}
echo $theCatName;
