Since the term "Guppy" is a hurtful to some of our wee widdle pywot's feelings. I order that we rename the 737-900 from "Super Guppy" to the "NeoSaur". Since it's a new airplane that performs slightly worse than a 1959 model B-707, "NeoSaur" is a very fitting name.
I decree, on this day as self appointed Lord of airplane nicknames and thereby De facto boss of Scrappy, the previous constable and monitor of all things aviation nickname, that the 737-900 shall be called the "NeoSaur" so it is said, so it shall be on this day of 26 July in the year of our lord, 2014.
SO THERE!!
