Do you know just how many official countries there are in the world? Or remember a time you actually had to leave your house to rent a movie? Were you aware that you can now Rick Roll someone in Klingon and would it surprise you to know that it takes 364 licks to get to the centre of a Tootsie Pop? All this and much, much more in Fun Video Friday.

To begin, Rooster Teeth show us what runs through a dude’s mind while he’s checking out girls. Possibly. Maybe. But guess what, girls get all tongued tied and super nervous too!

Movember 2013 kicks off in a few days so who better than the wondrous Nick Offerman to guide us through the best moments in moustache history. Lip scruff, yum.  Please take a moment to sign up to support awareness of male health issues.

Goodness, someone got out of the wrong side of the bed before opening BuzzFeed……

Talking of BuzzFeed (sorry Maddox), they take a rose tinted look back at the days of renting a video when you had to actually go to the store to do so. Hard to fathom in our second screen, cable TV heavy lives that there was once a time when you couldn’t rent a film if someone else had taken it out first.

Sh*t Nerds Never Say, filmed at Comic Con in NY earlier this month, does what it says on the tin. I know the comments about women in the industry are meant to be ironic but, wow, it’s still kind of depressing to hear.

Although Rick Rolling stopped actually being funny 15 years ago, when people go to the trouble of actually translating it into Klingon then they can have their 5 mins.

Who would have thought a simple question like ‘How many countries are there in the world?’ could be so complicated. And this is coming from someone who studied Geopolitical Relations at Uni. Luckily, the ever brilliant CGPGrey gives us the low down.

I cannot tell you anything about this next video because I am never going to watch it as long as I live.

Yay, Mental Floss bring us 38 sweet facts about candy, or 38 candy facts about sweets, if you’re from the UK. Puke flavoured lollipops FTW.

CinemaSins show us everything that is wrong With Paranormal Activity in 7 minutes or less which, considering it’s one of the world’s lamest movies, is an enormous amount to pack in. Dinny Time *shudders*

Your Supercut Of The Week: Slow Motion Running

Slo Mo running in real life, we’ve all tried it amirite? Luckily, there’s no need to break out in any kind of sweat to watch this montage of slow motion running clips from TV and movies such as Armageddon, Platoon, Chariots of Fire (of course) and Predator.
