Maybe it's because it was one of those shows I wasn't able to watch as a kid, but I have loved the show ever since I was able to. I know I don't even have to justify this being my all time favorite show. Everyone loves The Simpsons!
When I was visiting family in Hawaii years back, we noticed an airplane on the beach and thought it was a real airplane that had crashed on the island. We talked to the security guard watching over what we discovered to be a set for "some show called Lost," as he called it. I decided to watch it just because I was fascinated to see how it came out in post. Little did I know that my friends and I would become fans from episode 1.
Rescue Me is a lot of fun to watch, and not just because it's based around an entire fire house of all unrealistically attractive firefighters :). The plot lines have gotten a bit too extreme for my tastes on occasion, but I keep coming back for more to see where everything ends up.
