I saw your link already (even replied to it) but when I clicked on Weclocks I just saw a title like "teens in cat suits" and got creeped out and hit the back button before the thing started. Do these teens in cats do something funny and worthwhile or is it just to prove it's the same kids?
And "sick russian singing"... it just doesn't scream "click me while at work", you know?
The video about the two kids is apparently taken from the movie "L'or des Anges", a movie apparently about the tradition of boy's choirs. I could not find much info on that movie, but it appears to be divided in two parts, the first that follows a couple singers during their life with drama and all that (the scene is probably a metaphore of both the discovery of sexuality along with the discovery of homosexuality in an ambient that is extremely opposed to both (due to the religious background of these choirs)), while the second part should be a documentary on the history of the religious choir in Europe.
Basically one of those hard-to-watch artistic movies talking about something no-one else talks about.
So, the first link is perfectly safe and amusing to watch, the second is pretty creepy (it was probably the point of the scene) and the third is again perfectly safe to watch (just a video of Snoop Dogg's "Woof").
What do you mean with "sick russian singing"? Russian music is pretty awesome
to listen to! :p
