Happy Thanksgiving, folks! If you can, take some time out today to check Amazon’s Lightning Deals throughout the day, because there’s a great selection of items drastically reduced in price (DVDs for as low as $2!). All the items up for grabs are limited time only and limited supply, which means if you see it and want it, buy it immediately before either the sale ends or all items are claimed.

Of note, the Gold Box deal of the day is the Stargate Atlantis: The Complete Series Collection DVD box set for only $88.99 (that’s 66% off the list price of $259.98).

Everyone knows about the hilarious folks over at How It Should Have Ended, where they take the endings of popular movies and make a cartoon of what it should have been, right? They always point out the absurdities in those movies we love, which makes their endings oh so enjoyable.

They’ve done alternate endings for Superman Returns, The Matrix, and Tranformers. Now, they’ve released one for the ultra-popular teen vampire flick Twilight, which you can watch here below.

I think even the most sensitive Twihards will just have to laugh at what HISHE came up with. Oh, and there’s a post end-title cameo from another well-known vampire, so check it out.

As you can tell, there’s tons of sales going on this week, as a countdown to Black Friday.

This week, Amazon has a lot of DVD box sets on sale, one of which is for one of my favorite TV shows ever, Get Smart. For only $99.99 (that’s 50% off the list price of $199.95), you can get Get Smart – The Complete Series Gift Set.

This 5-volume collection contains all 138 original episodes of the 1960s TV spy comedy, which starred Don Adams as the bumbling secret agent Maxwell Smart and Barbara Feldon as his partner Agent 99. The episodes have been digitally restored and remastered and there’s over nine hours of rare footage and bonus features in this 25-DVD box set. For a detailed rundown of all of this DVD set’s bonus features, see the review of this boxed set.

Also on sale this week:

Also, for a limited time, are the Seinfeld individual season DVDs for $14.99 (that’s more than half off the usual price).

Rock legend Ronnie James Dio has been diagnosed with the early stages of stomach cancer, according to a statement posted on his official site by his wife Wendy Dio.

It was announced last week that the singer, who’s fronted classic hard rock bands, Rainbow and Black Sabbath, as well as his solo band Dio, had canceled his European tour after he was hospitalized.

According to the singer’s wife, who is also his longtime manager, Dio will be starting treatment immediately at the Mayo Clinic.

See below for the official statement regarding Dio’s health.

A couple of years ago, George Lucas himself gave the OK to Seth MacFarlane and Seth Green to spoof his classic Star Wars saga with their respective shows Family Guy and Robot Chicken. So far, we’ve seen a hilarious Family Guy spoof of A New Hope called Blue Harvest and two Robot Chicken specials. It has taken quite a while to get around to Family Guy‘s take on The Empire Strikes Back, but thankfully it will finally be released on DVD and Blu-ray December 22, 2009 and there is now a new trailer to watch via Apple.

The movie is called Something, Something, Something, Dark Side, which is quite fittingly a reference to a previous Family Guy joke. It will follow the basic premise of the movie, as they did the first time around, adding crude and silly humor wherever it will be allowed.

Click on over to to the dark side (baddum-cha!) to watch the trailer and read the brief synopsis for the movie. From this peek, it definitely looks like this could be just as funny as Blue Harvest was, and your time shan’t be wasted.
