Hey guys, I just wanted to add a little point of interest here regarding the "Orange-Sporange-Door Hinge" coincidence.
There is a phenomenon referred to as "Diegogarcity" that explains the sudden introduction of something which presumably has existed all along, but you're awareness of it hits you from multiple sources in a short period of time.
NPR had a story about this a while back, and while I'm paraphrasing here, they said basically the person who coined the term had recently learned about the Diego Garcia islands located in the indian ocean. Within days of this discovery, he or she talked to several people who mentioned Diego Garcia as a vacation destination.
I don't think any serious dictionary lists Diegogarcity, but its a fun word to use anyways.
