All these are really fun!
I quote Lotr a lot, but right now the only thing that comes to mind (and apropriately, too) is the "Filthy pop-ups! Wicked , trickssy, falssse! Curse them! We hates them, we hates them forever!" OT: there's a pop-up that keeps coming up asking me if I want to get rid of pop-ups! I mean, seriously...

How tricksy can you get?
btw - I was on another, non-lotr related forum a few days ago, and someone said she was getting 'gollumic' because of a link that was not working. I was about to ask her if she knows the 'Downs and this thread:

But then I figured that Lotr had become so much of a mainstream thingy, that these sayings probably entered into spoken language already. How cool is this? This is language in the making!
