I happened to type the phrase “rebus caneebus” into Amazon A9 today, which is strange enough in itself, but what’s even stranger is that A9 seems to think this could possibly be a USPS tracking code.

That’s kind of funny, if broken. It turns out that A9 sees alphanumeric strings containing exactly 13 letters or numbers and ending in “us” as a USPS tracking code!

So, for example, Doctor Faustus reads the Berlin papyrus and awaits the delivery of his bubble nucleus, the temperature falls one degree celcius, and in the continental US, where most of us play with pull down menus, A9 and the USPS track the whole thing!
