Bubble shows: Which will survive?

Super Fun Night "Monster Mash": It's a graveyard smash! Check out this Halloween-themed "Monster Mash" music video from the cast of Super Fun Night.

Andrew Lincoln vs. his beard: As Rick on The Walking Dead, Andrew Lincoln battles zombies week after week. But that's nothing compared to the real test he faces every day: difficulties with his beard.

Betty White spoofs "Wrecking Ball": Age ain't nothin' but a number, right? In this promo for Betty White's Off Their Rockers (now on Lifetime), the 91-year-old Golden Girls alum hops on the Miley Cyrus bandwagon wrecking ball and spoofs her infamous video.

Sarah Silverman's "Susan 313": Comedienne Sarah Silverman wrote a pilot for NBC last season called "Susan 313" that wasn't picked up by the network, but which Silverman has now made available on her YouTube channel. "This isn't like, 'Can you believe they didn't pick this up?'" she says by way of introducing the episode. "It's like, they probably did the right thing. But we liked the show." What do you think?

Children's Hospital Does "Roar": Get your Kleenex ready. Some staff members and patients at the Children's Hospital at Dartmouth-Hitchcock in New Hampshire put together a lip-syncing compilation video set to Katy Perry's "Roar." We just got something in our eye, we swear.

Dogs shaking in slow-mo: Is this super slowed-down video of dogs shaking and slobbering cute or disgusting? You be the judge! (We're still trying to figure it out.)

Kristen Schaal's sexy Halloween costumes: Bored with the typical "Sexy Nurse" and "Sexy Cat" Halloween costumes? Kristen Schaal has a solution. As she explained to Jon Stewart on The Daily Show, "Why don't we just show everyone what we mean when we put on those sexy ... costumes and take things to the obvious next level?" Check out her 2014 line of women's costumes, featuring a Sexy Vagina.
