Techno-Dummy Needs Help...Again

I give up.  Memes hate me.  You'd think it would be easy.  Enter the required information into the generator, paste the resulting text into the LJ, and presto, funny pictures, fractured holiday songs.  In a word: Fun!
But noooooo.  I paste my results into LJ and what do I get?  HTML coding.  That's what.  Even when I check it out from someone else's friend's page.
Would some kind soul, please, tell me what I'm doing wrong?
*whinge*whinge*whinge* 
Where's an emoticon when you really need one?  LOL
