Fred's strange addiction

Have you seen that TV show on TLC called "My Strange Addiction"?  I've only seen advertisements for it, I haven't watched it because it just kind of grosses me out.  Well, Fred has a strange addiction.  He's obsessed with licking the curtains.  He hasn't done it for awhile, but I was able to catch him in the act the other day.  I guess he's doing his part to make the house spic and span.
