I found this pretty entertaining. If you go to the official Triumph website, http://www.triumphtheinsultcomicdog.com/, then click on “Fansites” on the bottom, you will see a link to http://www.insultcomicdog.com. Follow the link, where you will see the following notice:

Got a message from the company that airs Triumph saying that I have to remove all Triumph stuff. So in the words of my generation — “F#%! NBC”

In fact, I found that two of the sites linked had this kind of directly noted C&D, whereas two more were dead geocities style pages. Pretty funny to sic the lawyers on your own links. Could be, that’s how the lawyers found them in the first place.
