Da Boom was my introduction to Family Guy, and it left a massive mark on my comedic taste. For a little context, it was the first show of its kind I'd seen, also; I had yet to see South Park, and only had a few Simpsons episodes under my belt. It didn't take long to realize I was watching a show unlike anything else out there.
People these days don't realize what a wild time it was back in '99 regarding Y2K. I remember my grandfather insisting it would be similar to a nuclear fallout, and he hoarded cans of food like a madman. That's what this episode touches on: the insanity surrounding the dawn of the new millennium.
I've been a Family Guy fan (especially of seasons 1 - 3) for a very long time, and to this day I firmly believe this is the best episode in the lot. An incredibly engaging plot laced with the comedy we're all familiar with (at least when it comes to early Family Guy), lots of character development and an overall great time.
(This is also the first episode to feature a Peter vs Chicken fight -- a bit which would turn up countless times over the years.)
