One of television's most beloved and historic television shows is undergoing a major change tonight.

Oh and it's also going to be in high definition too.

Tonight's episode of The Simpsons will update their iconic opening sequence for the second time in its 20-year history.

The Simpsons' main opening is one of the most perfect for just about any show of its caliber. It not only introduces the viewer to all of the characters, but it sets up their foibles, flaws and character traits better than any show could with an even bigger budget. It's immediately recognizable and iconic. Changing it would be like putting a trucker hat on the Mona Lisa.

But now that the new sequence has hit the web before the show hits the airwaves, my lack of exercise and general nutrition will be the only thing that keeps me from sleeping tonight. It doesn't mess with the opening that we've come to know and love over these last few decades. It builds on them. It adds new jokes in places you didn't realize jokes could go and gives some of the series' second and third tier characters a place to set themselves up before each episode. It's like they have used Ron Popeil's solid flavor injector to beef up their opening, instead of changing it altogether.

The only complaint is that they took out Homer's loud girly scream when Marge almost runs him over in the driveway. I've been watching the show since it came on the air and even now as a mature adult with taste, style and sophistication, I still laugh like a frat boy watching Steve-O do a butt chug when Homer utters that high pitched "Ahhhh!" as he runs through the garage. It's become so comforting and familiar that I'm not sure I'll enjoy an episode as much without it. It's audible heroin.
