JFC. I have loved this kind of situation for far longer than the Xzibit meme has been around.</hipster> I puzzle friends by excitedly pointing out trucks towing/hauling trucks of the same kind. I alienate people by getting wide-eyed at bags full of bags (no, not the grocery bags we keep under our sinks -- I'm inured to that). When I saw a picture of a tiny car (Fiat 500?) sitting in the back of a big SUV, one of my first temptations was to send it to everyone I know. I even flipped out when I first saw an oil rig being transported by ship, and that's only roughly related to what's going on in those other cases

Pictures of things performing their functions with respect to things of the same kind are to me what cats/weed/atheism are to stereotypical but non-existent redditors.

So, thanks. This is the second time I've wished I had more votes to deploy, excluding posts in which someone convincingly describes heroism such that I tear up.

(I realize that explaining an upvote is lame -- you voted something up: yes, you've expressed your appreciation, now stfu -- but I reckon I'm late enough to this thread that it'll escape notice.)

Edit: Upon re-reading that, I, for the first time, realized that my dissertation is about a type of the phenomenon I was just describing. (It's about abstract objects performing their functions with respect to other abstract objects, among other things.) Thanks for the epiphany, Iamsexyandiknowit.
