This is a thing that happens frequently on the Internet now, fictional character are pitted against one another in rap battles to test their hypothetical lyrical skills, and this time it’s two different crews of busters: Ghostbusters versus Mythbusters. Actually, I guess only one of the parties in this video is entirely fictional, but with a theme like this, it’s easy enough to overlook that in the most recent installment of Epic Rap Battles of History.

If you’ve encountered any of these videos before, you already know what to expect out of this new one. They’re fun enough for what they are, and if you’re into such things, this should prove to be a reasonably good time, or at least an adequate way to kill three minutes or so while you’re trying to run out that last bit of clock at work. Just try to keep the chuckles to a minimum so the people in the cubes around you don’t know that you’re up to anything fishy.

Mythbusters is light years better than the vast majority of reality TV out there (I’ve seriously been unfollowing people who tweet about Big Brother). And no matter how you feel about it, Mythbusters is about to undergo significant changes.

Hosts Adam Savage (the red-headed guy) and Jamie Hyneman (the guy who looks like a grumpy walrus) are the main faces of the show, but they’ve also have a trio of supporting players—Kari Byron, Tory Belleci, and Grant Imahara—as back up. Or at least had, because according to reports, the three members of the “Build Team,” who have grown quite popular in their own right, are leaving the show. It actually sounds very much like they’ve been fired, but since we’re not privy to that kind of insider information, we can only speculate.

We’re always excited when those explosion-crazed hooligans from MythBusters return from hiatus. After all, the show is built upon critical thinking and the scientific method, so it’s one of those great shows the whole family can watch together and learn something without even realizing it. (Okay, so every once in a while that lesson might be “How much damage will a wayward cannonball do to your house?”) The show returns with new episodes on Saturday, January 4, and the ‘Busters are once again pointing their debunking beam at an iconic bit of pop culture: the Star Wars movies.

Back in January, we told you guys about the guys from MythBusters putting out an open call for zombies for an upcoming episode that will look at different situations featured in AMC’s hit zombie drama (and something this site reports on every now and again) The Walking Dead. If you don’t remember, it’s possible the memory part of your brain might have been eaten out. In any case, we now know when we’ll be able to finally watch that episode. It’s a tad early for Halloween, but Discovery will be airing it on Thursday, October 17th. If you gobble down a bunch of candy bought for Trick ‘r Treaters while watching it, we won’t tell.

Thankfully they released more than just a release date, and named a couple of the themes they’ll be tackling. “Are axes or guns more effective at dispatching the undead?” is one of the troublesome questions they’ll try to answer, along with “How do those shuffling corpses always seem to catch up to their living prey?” While the weapons-based side of it is right up the alley of hosts Adam Savage and Jamie Hyneman, that second question sounds like it’ll be more complicated. Unless they just bring on Jason Voorhees to explain that people just get tripped up on their own feet way more often than one might think. It’s too bad one of the questions isn’t “How many punches does it take to make Carl cease to exist?”

It’s finally the cool weather month of ghouls, goblins, and the cold tits of witches. Oh, and zombies, of course. And here on this week’s Cross the Streams, not only have the undead risen, but there was just too much interesting material to limit to just one feature, so we split them up into TV and movies. There’s no way in hell you guys should be bored this week. Unless you’re a naturally miserable person. But then we have something in common. Stream on!

The Walking Dead: Season 3 (Netflix Instant)
The best season yet of AMC’s The Walking Dead, which isn’t saying all that much, these 16 episodes are chock-full of awesome-looking zombies and slow-moving conversations. Comic fans rejoiced as the blade-wielding badass Michonne and the psychotic despot the Governor joined the cast, and the prison setting was used with some success. Lots of twists and surprises this season lead into what looks like an explosive fourth installment, which begins on October 13th. If you haven’t caught up yet, I see a shambling marathon in your future.

The Giant Freakin’ Robot staff would like to take this moment and ask everyone to join us in a standing ovation for the guys from WIRED for creating the most incredible example of cosplay ever exhibited. And while their Freakin’ Robot, which they call the WIRED Mech isn’t giant in a relative-to-Pacific Rim‘s Jaegers kind of way, this 9.5-toot-tall, 400-pound behemoth would gut punch me into tomorrow if it heard me talking bad about it. Unleashing this hulking menace of a costume at Comic-Con 2013, WIRED is obviously dead set on both eventual robotic dictatorship and making a lot of people giggle nervously as their brains imagine a futuristic world with these things walking around everywhere. That is before their tyranny begins and all humans are vaporized out of existence.

After the WIRED guys conceived the idea, they got the masters at the Stan Winston School and Legacy Effects to turn it into a massive, technically-sound robot, controlled by a human standing inside. Far more complicated than a costume gag on Scooby-Doo, the Mech and its 12-foot wingspan incorporates an extremely precise control system, so that the bot is a walking representation of the pilot himself. And since you can’t have something this large demand the end of humanity with the voice of a human itself, there’s some vocal distortion.
