I found these parodies on newgrounds.com. Of course, I'm not anti-LU, but the guy that made these seems to have had the same impression alot of us got when we first layed eyes on the tics. And they are pretty funny if you take it from his side of view.
WARNING: They have EXTREMELY explicit langauge, just so you know.
Now, I personally think its very plausible they only thought up LU to make money, but dont all cartoonists make a living out of cartoons? I also think LU is written better, and more entertaining then ALOT of the other crap I've seen being spit out of the cartoon industry.
