I'll explain later...

Long term book lending to friends reminds me of medieval noble hostages. You exchange them in hopes of prolonging and improving your relationship, security for your items and eventually they become part of your household.

After seeing Age of Ultron, I’ve decided that UltRon Swanson should be a thing. 

The fact that I can find documentaries and other childhood favorite videos on the internet always reminds me how amazing it is. 

I don't think I find anything as uniquely irritating as being unable to find the music used in documentaries. I can find the music from black and white movies, an eclectic mix of international artists, and video games that were never released in my country. One or two minute clips of documentary background music? Impossible. I literally can find music about unicorns more easily. Therefore, musically, anything to do with a documentary is rarer than a unicorn.
