I just discovered FT this past summer and totally fell in love with Loke and Lucy. I've been writing a story on the two of them on Fanfiction.net (shameless plug: "Lion's Pride") and one of my readers got together a bunch of us fans to write about Loke's affects on catnip. Since I actually own cats, I know the silliness quite well. Even though I wrote this, it makes me crack up every time. Seriously, I would love Hiro-sensei for life if he made an episode like this!
You can also find this story on Fanfiction.net.
