A viral video is one that becomes popular through the process of Internet sharing, via social media, sharing sites, or good ‘ole email. Everyday we highlight some of the best that are currently viral and some that are trending that way.

Today’s videos feature Hangover: The Penguin Thieves Edition, The Avengers (on a budget) trailer, and simple but amazing use of slow motion.

Here’s what a marijuana PSA looks like if you’re tripping on something. I really hope those people got found though.

Maybe the best thing Seal has ever provided the world. Ok, so Kiss from a Rose was the most tolerable aspect of Batman Forever…but that’s not saying much.

1 of 2 things is happening in this video. Either Bill Nye is just dancing horribly, and has an extreme case of not giving a damn — or — he’s tripping on something with the name “feel good” in it. Either way it’s equally awesome.

Who knew bears were such chumps…

The guys in the video were really sorry, and let’s be honest who HASN’T had one of those kind of nights take place? It’s just good to hear the penguin made it back safely.

Slow motion, the way God intended…

I think Hawkeye will have that amount of screen time in the actual movie.

So many fat cat jokes…at the very least the cat will be too lazy to climb on your stuff. Oh, I was tricking you a bit with the “600 lb cat inside” above. That’s the equivalent if the cat were a person, still amazing though.

So much work throughout the years, at the very least the kid looks like he was having fun during the whole experience. As a dad, it was probably very interesting and heart-warming in the editing room.
