Years ago, like around 2000, I had a personal blog where I mentioned a local TV celebrity talking about something. The post was about 90% the topic, but in referencing the guy himself, I said something like, "this guy's cool." The local celeb had a trademarked moniker "The Car Czar," and I used it in reference to him.

I swear, on a busy week I had about 5 people reading that blog and they were all coworkers. The next day, I had a 6th visitor from Los Angeles and got excited. Who was this mysterious visitor? I found out when I opened my email and saw a C&D from Universal's lawyers saying I was abusing the trademark.

I blogged the next day, "Wtf, Universal?" and a few days later, got an email from the local celeb apologizing for the overzealous legal team. He was indeed totally cool about it.
