Songwriter Vic Mizzy has died, reports the Hollywood Reporter.

Mizzy is also one of many songwriters featured in our ongoing Best TV Theme Songs tournament. Both 'Addams' and 'Green Acres' are poised to make it past the inaugural round of 32, which closes later this afternoon.

On the heels of last week's shocking round 2 results (yep, we're still bitter about 'The Mary Tyler Moore Show' losing), AOL TV users pulled another fast one on us in round 3, ousting front runner 'M*A*S*H' in favor of 'Happy Days.' So much for suicide being painless.

'Happy Days' now joins 'The Andy Griffith Show,' 'Gilligan's Island' and 'Mission: Impossible' in the next stage of our 5-round best TV theme songs tournament.

Only two can make it to next week's final round of voting. Which will it be? Vote now and then come back on Nov. 11 to see the results.

Just sit right back ... say goodbye grey sky and hello blue ... because we're movin' on up ... to a place where everybody knows our name.

Everybody's got a favorite TV-show theme song -- or 10 -- they can sing or hum along to in their sleep. That's why we're asking for your suggestions for the catchiest openers to include in our Theme Song Throwdown this month. The best 16 theme songs will be paired off in a bracket-style tournament (think March Madness), then you, the fans, will vote. The winner of each match-up moves on the next round until a Theme Song Champion is determined.

Perhaps you loved to whistle 'The Andy Griffith Show' theme song (as close as you could get, anyway). Or you could recite the 'Fresh Prince of Bel Air' opener from heart ("Now, this is a story all about how my life got flipped, turned upside down ... "). Or maybe you tormented your parents by screaming "Greeeeeeeeeeeeen Acres is the place to be" at the top of your lungs (we know from personal experience that it worked very well). Now's your chance to share your fave -- and who knows, maybe it'll be crowned grand champion of the television theme songs.

So, which theme songs deserve to be in the sweet 16? Post your nominations in the comments.

Zachary Johnson and Jeffrey Max are two effed up dudes.

Before they hit the "viralsphere" with Lasagna Cat, the production team and creative geniuses behind Fatal Farm created an incredibly twisted, brilliantly subversive, and unarguably hilarious series of "alternative intros" parodying the openings to classic sitcoms. No two intros follow the same theme or formula, except to say that they're all unequivocally... Messed. Up.

From blood and guts to go-carts and the hinting of pedophilia, each parody brings with it an innate ability to eviscerate any leftover nostalgia from the sight of, say, the Happy Days jukebox or the beginning chords of the theme to Cheers. (Believe us, you'll never think of Rhea Perlman the same way again.)

Strap in, sit back, and take an incredibly disturbing trip down Memory Lane, courtesy of your friendly tour guides at Fatal Farm:

Eric Deggans, the TV and Media critic for the St. Petersburg Times has an interesting article up discussing the death of the TV theme song and also providing a list of his top-ten theme songs of all time.

Deggans points out the obvious -- that TV producers, ever wary of viewers flipping channels, have tried to keep the start of the show as peppy as possible -- but he also ventures a theory that is in desperate need of further explanation....
