F4LL0UT: I'm pissed since I learned the order of the planets with the aid of this German mnemonic (where every word starts with the first letter of the corresponding planet):
Mein Vater erklärt mir jeden Sonntag unsere neun Planeten.
Now it's not correct anymore because it covers Pluto and says "our nine planets". Stupid astronomers...
Yeah, there was a Polish mnemonic as well:
Moja Wiecznie Zapracowana Mama Jutro Sama Upiecze Nam Placek
But it doesn't make much sense because it's not connected with planets whatsoever. The English one, however, was pretty good:
My Very Easy Method Just Set Up Nine Planets
But seriously, the decision was right...
