I never really got into this series when it originally aired, but I decided to check it out more thoroughly when I first got my Netflix membership, back when they mostly just mailed you DVDs. I now own the entire series, and it is seriously probably my very favorite show of all time. I've definitely watched it more than any other show, and something that's kind of odd for a comedy, it's still just as funny with every single re-watch. I literally never get tired of it, and I laugh just as much every time. I may go a little while without watching it, but when I do, I'll re-watch the entire series from beginning to end, usually one episode every night before bed. So many great comedians on here, and a lot of them before they were really big, if I'm not mistaken. Aside from the comedians, just the general comedy of the show and its characters is top-notch. Some of the best comedy writing ever! My favorite character is the video store clerk, Todd, voiced by comedian Todd Barry. And one of the main characters, Dr. Katz's son, Ben, is voiced by Jon Benjamin, in what was probably his first gig, and arguably some of the funniest stuff he's ever done. Great show all around!
